@danishsuri123 Were you able to fix this? Apparently, for me, this is happening on iOS/iPAD OS 15.

I have the same problem. I tried with Firefox and Chrome (Incognito window), and it works well. However, it fails to connect in Chrome normal mode.

I have just got this issue as well (Chrome 116). No idea why. Incognito window works well. This is crazy.

Oh, Clear Site Data in Google Chrome fixed the issue!
F12 -> Application -> Storage -> Clear Site Data (button)

At first I have tried deleting local storage manually but that didn't help. So glad this global clear function helped.
