Are you able to bind to any port between 3000 and 3001 with other frameworks?
Can you create a Next or Vite project for example?

[jifffffy]

yes, I am sure no ohter process bind port 3000 and 3001,
it is ok when I run on the windows and mac. this is not the first my remotion project, but this is the first in the wsl.
I reboot the computer. but I still get the error.
thanks very much your quickly replay!

in get-port.ts file using the host addrest 127.0.0.1 and 0.0.0.0. cause that socket connect timeout
127.0.0.1 and 0.0.0.0 in wsl cannot access with any port. should use a real ip address.
if I remove the ipv4 address, everything is ok.

[JonnyBurger]

Thanks for investigating - What is a real IP address then?
If localhost is not available?

[JonnyBurger]

Maybe we should copy the logic from Vite

https://github.com/vitejs/vite/blob/21ec1ce7f041efa5cd781924f7bc536ab406a197/packages/vite/src/node/utils.ts#L933

[jifffffy]

The real address can get in the wsl as follows:

ip route show | grep -i default | awk '{ print $3}'

so it is good passing as a flag to the cli.
