@girish Yes these are the certificates issued yesterday, because I put the server back up last night to move the applications from the old server. It was fine with the certificate until this morning. At work, the certificate started failing. I did a certificate refresh several times, cleared the browser and tests on several office devices and the error continues to appear.

EDIT: Now I reinstalled Cloudron but with manual settings for the domain with a Polish provider and it works fine so far. The certificate generates and displays without error. We will see in a few hours.

I seem to have found the cause. It is probably related to the API of the domain providers. I did a test with 3 providers.

Hetzner DNS - no problem
GoDaddy - problem
Manual (domeny.tv) - no problem

EDIT: Sorry for the edit. One more test I did I used the domain that is in GoDaddy, having my.yyy.xxx-xxx.tld for manual settings. An error appears with the certificate! I have a feeling it's a problem with GoDaddy DNS or by the "-" in the domain.

Hello,

I also report a problem with the certificate having on the domain yyy.xxx.tld
I noticed that the problem is common in many browsers - Firefox, Chrome, Brave and Vivaldi on the computer - the error pops up, and on Edge there is no error. On mobile devices - there is an error on all browsers.
