SOLVED Recently started seeing "An error occured while communicating with the mail server" errors

[adrw]

Calendar and contacts seem to still work but all email doesn't show up amidst this exception. I'm not sure where I can find the logs on the Cloudron email back end to diagnose further. I've tried restarting my Cloudron and SOGo. Rainloop and other IMAP clients still connect without error though my iPhone started complaining about expired certificates so I was forced to delete those accounts and reset them up to get them to work. I'm suspicious that SOGo may have saved an out of date certificate and that is why it is erroring.

I'd appreciate any help or guidance in diagnosis! Many thanks!

I think maybe the mail server certificates expired/could not be renewed for some reason. Can you please try this:

• Domains -> Renew all certs
• Then Services -> Mail -> Restart the mail service

After the above two, does iPhone still complain? If it doesn't, can you then check if SOGo works after that?

@girish Perfect! That did the trick, many thanks!
