Cannot connect to imap.zoho.eu on iOS26

Cannot connect to imap.zoho.eu on iOS26

Hey,

I recently migrated to another iPhone and since then use iOS26. Every since then, I was not able to connect to "imap.zoho.eu" from Apple Mail. I tried deleting the account and adding it again, did not work. I tried creating an app password, didn't work.
Why is iOS26 not able to connect to the imap server? I checked the server connection from a different machine on my network, it works fine. Only iOS is making problems.

Did anybody else have this issue?
