Seems like a bad connection. Probably Telegram is blocked in your country or you are behind a proxy of some kind.

Also, don't edit the template where it asks specifically to try the latest development version from github.

Oh thanks! I forgot about it already :)

closed this

@delivrance, It seems to me that a fix would be a good reason for closing, which gives a more understandable error message. "KeyError: 0" -- this message does not carry useful information to the user. It would be nice if there was a connection issue message :)

Oops, yes, here I was wrong, I apologize

Hello! When I start the client in docker, I got the same error but I don't use some proxies and tg is allowed in my country. But not using docker everything is fine :(( What could be the reason?
