IMAP server is not reachable

"imap server is not reachable" message received when trying to access protonmail from nextcloud using either Auto or Manual selection. Using suggested settings: IMAP Host 127.0.0.1 and Port 1143; SMTP Host 127.0.0.1 port 1025. Both using STARTTLS. Any idea of how to fix?
Thanks!

The standard IMAP ports are:

  • 993 for imaps (IMAP over TLS); and
  • 143 for imap.

Are you sure your nextcloud settings are correct?

Also, if nextcloud doesn't live on the same machine as the IMAP server, then you need to use a different IP address (not 127.0.0.1…aka localhost) as well.
