Cannot Create any mails NO [AUTHENTICATIONFAILED] Authentication failed

I have NextCloud 23.0.0.3 with a Mailserver using PostFix and Dovecut and SSL (certbot.eff).

I followed this guide >>thisGuide<< in the installation process.

I followed it step by step but the issue appeared on the last step while I’m trying to create a new email to the server

I keep getting

reating account failed:Connection to IMAP at :993 failed. Authentication failed.

on horde_imap.log

Connection to: imap://:993/
Server connection took 0.0132 seconds.
S: * OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ AUTH=PLAIN AUTH=LOGIN] Dovecot (Ubuntu) ready.

and the NextCloud.log

details i add to the new email

I’ve also tried different names and simpler passwords and more complex once, they all endup the same way

I checked all the required ports I cant find any issue and as for nowufw is not active.
I’ve looked all day all over the internet, and tried all the answers I could find, I can’t figure out why it’s acting like that.

Hi @JoyX2

I googled the ERROR: read/timeout error. S: 2 NO [AUTHENTICATIONFAILED] Authentication failed message and found this…

Hope that helps…
