Error on :ERR_CERT_COMMON_NAME_INVALID

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

Hi,

We have a nginx webserver with websocket listening port: 4297

We have configured a proxy that listens port: 7777 ssl and forwards it to port: 4297

When we try connecting without using ssl with ws everything works fine, but when we add ssl when our app tries to connect with port: 7777 we get this error in return:

> NET::ERR_CERT_COMMON_NAME_INVALID.

We already did several tests but we always have the same results. What are we doing wrong?

Thank you.

Hi @IvanZD

there is a working port 443.

Port 7777 doesn't answer. So where runs that port 7777?

Use the port 443 as template.

Additional problem with a wss: Sometimes the ip is used to connect the webservice. That's always wrong, check, if the domain name is used.
