Maybe this has nothing to do with you. I confess I’m a little desperate. All I need is to resolve this problem: ERR_CERT_COMMON_NAME_INVALID
This is what shows on my browser console when I try to connect via the code wss://my_ip:443, where 443 is the port. I asked for help at other groups/communities and all of them have said the same thing: that I need to check if there is compatibility between the certificates both in the websocket and in my web server (my site follows this pattern: https://mysite.com). By looking up my files dependency, this is what I found:
This file cacert.pem is the ca bundle that contains various certificates in PEM format. Inside that document, I couldn’t find any Let’s Encrypt certificate. Where can I find one, so that I can put there just to test? I know that I used CertBot to install and enable https in my website, so I thought that maybe you could help.
