"The operation was cancelled"

[Antonio-P8A]

Hello, I’m using the library and it’s really good, but yesterday it was working without any problems. Today, though, it’s giving me issues and it only returns:

{"type":"error","message":"The operation was cancelled"}

It doesn’t give me any additional reason, so I can’t tell what’s going on.

You need to generate the MadelineProto log, and it will tell you what the problem is. In my case, it was a clock desynchronization, and it was enough to run sudo timedatectl set-ntp true and everything worked again, because Telegram generates IDs based on time.
