Hello @rTiRe!

This may be a problem on the telegram servers side.
This may be due to support/compatibility issues with the old tl schema (it hasn't been updated in over a year).
See this comment.

If it's reason 2, then try using a fork with a fresh schema, like this one.

Also I get:

ValueError: The server sent an unknown constructor: 0x94345242

ValueError: The server sent an unknown constructor: 0xabb5f120

ValueError: The server sent an unknown constructor: 0xaadfc8f

ValueError: The server sent an unknown constructor: 0x4fe1cc86

Привет@rTiRe!

Это может быть проблема на стороне серверов Telegram.

Это может быть связано с проблемами поддержки/совместимости старой схемы tl (она не обновлялась больше года).

См. этот комментарий .

Если причина 2, то попробуйте использовать форк с новой схемой, например, такой .

Thank you, I will try this!

I don't think it's my case that it's point number three, because I often get the same codes rather than different ones, which would probably be the case if I receive mixed updates.
