Describe your issue
Hello all 
I realised I had an issue with my domain certificate, after not being able to access my server, and running diagnosis run showed that the ports were the issue, and looking at the output of the diagnosis showed the issue came from the certificates. Running yunohost domain cert renew brought up the following error: Something wrong happened when trying to open current certificate for domain my-domain.noho.st (file: /etc/yunohost/certs/domain.noho.st/crt.pem), reason: [('PEM routines', '', 'no start line')]. I then tried to run cat on the mentioned file and saw the file was empty. After looking around, I bumped into this topic on the forum, and decided to try to remove the above mentioned crt.pem file, then run yunohost tools regen-conf ssl. This did not help unfortunately and now I get the following error: Could not read the certificate file for the domain....
Does anyone have an idea what can I do, or try to do, to get out of this mess? I’d truly appreciate any help
