Unrecognized Certificate (Email Client) [Solved]

I recently created a disroot email account and implement on K9 client.

Unfortunately there was a Certificate error and nothing was shown at the tutorial here: https://howto.disroot.org/en/email/email-clients/mobile/androidk9

Personally I think it’s because Let’sEncrypt reuses/recycles certs. Any thoughts?

Hey,
By looking at your screenshots i see that you used imap.disroot.org.
The right setting for imap or smtp is disroot.org,
So no imap, pop, or smtp before disroot.org.
You can find more information on
