Internet access does not work (abuse prevention) #158

showstoppre · 2022-03-03T17:56:33Z

0 B received. Handshake did not get completed.

I thought it could be account issue. Registered a new account from a VPN and tried connecting with the new config.

Still same.

Edit from maintainer:

Just to give some organization to all the "internet does not work" reports. There are two known cases when this may happen:

If the WireGuard tunnel works on your other computer/phone, but not on this one, then it's likely an issue with your system configuration. It's generally not something I can help with, as wgcf is only responsible for providing you with a WireGuard profile, but leaving this issue open for people to share their experiences and solutions. This is tracked in Internet access does not work (system issue) #50.
If the WireGuard tunnel does not work on any of your devices, but the official client does, then this is likely an issue with your region being restricted due to abuse prevention. There is no solution to this problem, maybe hope that people stop abusing the service so the regions are unlocked. Use the official client in this case. This is tracked in Internet access does not work (abuse prevention) #158.

ViRb3 · 2022-03-03T17:57:20Z

See #50.

showstoppre · 2022-03-03T18:02:52Z

Thanks for the swift response. I checked there before posting this. I'm on windows. I don't think whatever I'm facing is related to that thread.

It was working fine until an hour back and never had an issue since I started using this for about 2 months.

ViRb3 · 2022-03-03T18:05:35Z

My general response would be to test this on a fresh Ubuntu 21.10 installation and see if it works there. If not, it's definitely an issue with your Windows installation. Otherwise, could be a ton of different things that guessing would be impossible. FWIW, everything works fine here on macOS and Ubuntu.

showstoppre · 2022-03-03T18:09:01Z

got ya. thanks. I'll check it out. But it is weird that it was working fine until an hour back.

So I don't think it is a windows issue.

AdroitAdorKhan · 2022-03-03T18:41:28Z

I am facing the same issue here. It suddenly stopped working an hour or two ago.

Juancollado2003 · 2022-03-03T18:41:50Z

wgcf suddenly stopped working today all over, it's not windows fault, looks like cloudflare banned it

showstoppre · 2022-03-03T18:42:18Z

@AdroitAdorKhan @Juancollado2003 are you guys on windows too?

ViRb3 · 2022-03-03T18:43:29Z

I can confirm the issue, just started happening to me on macOS too. Will try to investigate soon.

AdroitAdorKhan · 2022-03-03T18:43:33Z

@AdroitAdorKhan @Juancollado2003 are you guys on windows too?

Windows 10, Debian 11, Android 11 & RouterOS 7.x. Confirmed, not working anywhere since last 2 hours (maybe).

AdroitAdorKhan · 2022-03-03T18:48:47Z

I can confirm the issue, just started happening to me on macOS too. Will try to investigate soon.

Could be CF changed host address or port?

showstoppre · 2022-03-03T18:51:41Z

I'm not sure if this is anyway related.

Cloudwarp windows client works fine for me. So I tried capturing traffic using wireshark to see if there is any difference in packets.

What caught my eye was, there is a field called wg.reserved which has value b91981 in all "wireguard protocol" traffic via warp client.

For the traffic via wireguard client, this value is 000000

showstoppre · 2022-03-03T18:54:28Z

I can confirm the issue, just started happening to me on macOS too. Will try to investigate soon.

Could be CF changed host address or port?

Port seems to be the same. Native warp client uses a different IP. I tried with that as well. But it didn't help

beygolu · 2022-03-03T20:44:41Z

Many people are having the same problem, I hope it gets resolved.

PussAzuki · 2022-03-03T21:17:32Z

I also encountered this problem, and I noticed that I could get a response from the end of the 6in4 tunnel, but warp showed that all the services that depended on it offline were down.

I thought the 6in4 tunnel of HE was broken. I tried to dial again many times and checked the server status page of HE. I noticed that I could get from the opposite end of the 6in4 tunnel. Everything was fine when I only used 6in4.

icsterm · 2022-03-03T21:20:36Z

This is weird, I'm using WARP on a Mikrotik router, stopped working 3-4 hours ago.
So this is not OS related, it must be server related.
Basically i get no RX packets and no handshakes.

ViRb3 · 2022-03-03T21:24:07Z

I have just received an unofficial response from Cloudflare. Indeed, unofficial clients like WireGuard are blocked server-side due to huge amount of abuse. Exactly what form of abuse I do not know. However, the block is expected to be lifted later today, and I am working with them on a long-term solution. For now though:

⚠️ Please do not use wgcf to abuse Cloudflare WARP. If wgcf allows you to do something different from using WARP on unsupported devices, please stop. Doing so will get all of us banned permanently.

showstoppre · 2022-03-03T21:35:23Z

The block seems to have been lifted. It's working for me.

ViRb3 · 2022-03-03T21:38:41Z

I can confirm it works here too. Leaving this issue for visibility, though.

gvccvwangmingn2 · 2022-03-04T02:18:08Z

prepare for the worst, use the warp-cli for linux or official clients for windows/macos.

since the beginning cloudflare never supports unofficial clients or use own wg config for WARP, so don't cry if they block it again...

ghost · 2022-03-04T04:25:19Z

First time trying out wgcf but I have no internet. No idea if it's my setup or it's being block again.

Get "https://api.cloudflareclient.com/v0a1922/reg/aa72d4c8-f9b6-41ba-849f-667451dfec47": dial tcp: lookup api.cloudflareclient.com on [::1]:53: read udp [::1]:35982->[::1]:53: read: connection refused

Using Fedora Silverblue with nmcli

theSaSo · 2022-03-04T04:33:17Z

Mine on Windows doesn't work either. Perhaps the block was re-initiated.

Fearyncess · 2022-03-04T05:28:51Z

ipv6 endpoint seems be removed?

Bleestones · 2022-03-04T14:51:36Z

Now, it is working!

lehoangnb · 2022-03-05T04:25:23Z

Hi, did you change anything?? still doesn't work for me

zengxs · 2022-03-05T06:10:36Z

Now, it is working!

Hi, did you change anything?? still doesn't work for me

It seems to be region related, I tested Tokyo's network already works, but Hong Kong's still doesn't.

bachvnnvn · 2022-08-12T02:53:05Z

2606:4700:d0::a29f:c102

Sorry, still doesn't work. Yes, let me try Android Studio.
Thank you!

here is the tutorial link https://parkercs.tech/cloudflare-for-teams-wireguard-config/

I got the file, but the private key seems to be encrypted. Could you please tell me how to decrypt it?

string name="warp_private_key">XXXXXXXXXXXXXXXXXXXXX ]+yGW5Y6BignXXR3uZDB2MaM/pzj0Y0YThYezBYqGY84CQC/TUKHJ4bXDF8m3wL4VkP6qkVG3W2b3 y/5n

There is no way to decrypt private key unless using old android system version and specific device definition. That's the reason why I put the tutorial link

Yes, I could get the decrypted value with the old android version.
Thank you very much for that!

But I still cannot connect, it shows "Failed to send handshake initiation" (from Wireguard android).

I used the below endpoint:

endpoint":{"v4":"162.159.192.8**:0**","v6":"[2606:4700:d0::a29f:c008**]:0**"}}]

I can see the port there is :0 and the config file also has the below value:

"services":{"http_proxy":"172.16.0.1:2480"}}</string>

So looks like it doesn't use the port 2408 directly but forward to the proxy 172.16.0.1:2480

PeakGymnast · 2022-08-12T04:23:29Z

But I still cannot connect, it shows "Failed to send handshake initiation" (from Wireguard android).

So you are running this config file on Android？
If you are running on Android，you need to change your AllowedIPs to 0.0.0.0/1, ::/1. Therefore, you said that your endpoint port was an invalid value of zero which means that you are wrong to get your config. you should let official warp app connet vpn successfully or using global proxy in order to connect cloudflare warp, then pull the config file

endpoint":{"v4":"162.159.192.8**:0**","v6":"[2606:4700:d0::a29f:c008**]:0**"}}]

I do not know exactly what to do and how to fix. As far as i conclude, your ISP may block UDP Protocol or connection redirects to re-routed server.

This program has continued a period of time for me, i used to suffer the same issue when using ipv4 on pc and mobile phone. But when i intend to run ipv6 ,it works for me even cellular network in China where it widely known that censorship and firewall block

My config 👇👇👇👇

bachvnnvn · 2022-08-12T05:10:12Z

::/1

Sorry, it still doesn't work for me.
I decided to give it up.

Anyway, thank you very much for your great help!

n-buna404 · 2022-08-26T03:09:13Z

Without changing any configuration, it just suddenly works. Warp connected me AMS colo instead of HKG.
Hope that's the end of the issue

dongle-the-gadget · 2022-10-11T08:37:53Z

Update: There's a project that re-written the whole ptorocol in Go, but it's half-sourced (core part, most were open-sourced).
I've the source code and after audit it's safe to use.
Project link here

Edit: This is also an unofficial client, use at your risk.

dongle-the-gadget · 2022-11-10T17:22:42Z

Looks like the HKG server once again went dark.

dongle-the-gadget · 2022-11-11T10:51:27Z

What’s the affected colocation, and how did they abuse it?

worstperson · 2022-11-11T14:09:38Z

What’s the affected colocation, and how did they abuse it?

DFW reroute to LAX afaict, with absolutely insane ~2TB monthly usage mostly through legit video services. But he hasn't had to reconnect his tunnel yet and reports working service for now.

Very nice, works fine with Fedora 37.
Only other setting I have changed is the MTU value from 1280 to 1420 (for PPPoE/DSL set it to 1412).

For some reason, Cloudflare warp team has modified official wireguard protocol, which means you won't be able to connect wireguard to warp as usual. People found out a unique value unlike official wireguard protocol, you can see this link Xray-examples-reserved id

By this time, I'd like to suggest you using Sing-box(a powerful tool) to make connection because of its better performance than official wireguard client
