Have you tried removing and re-adding the account? (Can be annoying if you have per-account settings like signatures, so be sure to back them up first!)
Yes, i did this few times. also i checked FAQ my provider to configure it well.
Does the same problem appear when you use a different mail client? It’s possible that the email provider’s having issues, if it’s just been a few days. It may also be worth trying your mail provider’s support team, in case some config has recently changed on their end.
The only other thing I can suggest is switching to the deb install (given you’re using Ubuntu). I had more problems with the snap than the deb (although this this particular one).
i sent mail to my provider support and im waiting for their response.
ok, ill try use instalation from .deb except snap, i hope it will help
#edit
instalation from .deb didnt help
