After the recent update, one of my mail accounts has stopped working on both IMAP and SMTP. I have tried:
Resetting the credentials
Running the Diagnostics and Fix
Restarting emClient
The same account was working without issues for years in emClient prior to the upgrade and works fine in the BlueMail client on my Android.
Gmail seems to work OK (
).
I turned on IMAP logging and got this (“####” represents my redactions):
