Roundcube hangs on "Loading..."


after upgrade to 1.2.1 when i try open roundcube https://webmail.domain.tld it kepping loading for long time.
after i stop and login again it login fine.

Anything relevant in dovecot logs?

Same thing happens to my servers after creating new domains.

It’s loading until I click on the refresh button, then I get logged in. But happens just once when you create a new domain with mail.

Yes me too also new email not pass the test 2.9/10
Dkim and Dmark issue

I just can repeat @Lupu question: Anything relevant in dovecot logs?
