Hi there.
Today after restarting Cloudron service (it asked about restart due to some security reasons) my mail clients stopped connecting to IMAP with errors related to the SSL certificate.
I tried to renew certificates through the admin panel but this didn't help.
Here how it looks from Thunderbird client. First, it says that certificate information is outdated:
After clicking on Get certificate button it says that it can't get information:
How can I fix this issue? At the moment I can use email only trough SOGo client.
