Hi, Since latests Android release ( on my Galaxy S23) I regularly have the following error: System.Net.Sockets.SocketException (103)

Sometimes it works although no changes made in my config

I use
IMAP protocol with imap.mailfence.com /993/TLS on a legacy port
SMTP protocol with smtp.mailfence.com /465/TLS on a legacy port

Any idea to fix the problem ?

Hi team, I think I have found the issue.

I Have recreated the account but same problem.
Then I checked the VPN ( Avast) and this one was creating the problem because stopping it did prevent the error to raise.
Now the question is: why was this problem not coming in the past ?

I have switched to Proton VPN and now everything runs smooth.
