NET::ERR_CERT_COMMON_NAME_INVALID

Hello,

Since I made an update on the server today I can’t reach the panel anymore (Thunderbird can’t connect either):
NET::ERR_CERT_COMMON_NAME_INVALID

What can I do, can someone please help me?

Thanks in advance.

This only happen after updating following packages on ubuntu 20.20:

containerd.io docker-ce docker-ce-cli libparted2 libssl1.1 linux-firmware
openssl parted

I had imported an old snapshot, then it worked again, but after the update it did not work anymore?

A bug in MailCow?

EDIT: It only happens after updating to the latest version of MailCow

Yes l, it is and this make it workable as befor:
mailcow/mailcow-dockerized835c4ee

I had panic this morning 😅😅
