Server disabled after certificates deleted

I am running an instance of openvidu server on https://tvujjazykovykouc.cz:444/. My web browser started to report “the certificate expired on … unable to connect”. So I followed this discussion - How to regenerate SSL certificate - #5 by OgtayTasinov - I deleted the certificates directory and I restarted the server. This is the output - everything looks fine to me - unfortunately, it is not possible to connect to the server at all now:

Please, could anybody advice, what is wrong?

I’ll close this because it is being talked here: How to regenerate SSL certificate - #23 by CraosCZ
