Questions

For imap login block and key check, but an error comes out

ImapLogin (ImapLogin) <<

[SAFE MODE] Exception caught and saved to data.ERROR: System.Threading.Tasks.TaskCanceledException: A task was canceled.

Any suggestions on it. By the way, the similar check is working on ob1,
thanks

sometimes, this error,

[SAFE MODE] Exception caught and saved to data.ERROR: System.IO.IOException: The read operation failed, see inner exception.

Do not know why

A task was canceled usually means a timeout. As for the second one, no clue. Are you sure the server works and the credentials are correct?
