QUESTION
when some players enter our game, they meet this error in all browsers
We have changed the certificate recently. So I check one player's certificate on our game page,
It is the lastest certificate. So what may cause this problem? Should we do something after change the certificate?
EDIT1
Did CDN cache the certificate? After we refresh the CDN, some player can connect to the game immediately.
EDIT2
We found the player's browser has such an option "block unsafe certificate", when the option is enabled, he can't connect to the server and he can connect to server when the option is disabled. We export the intermediate certificate and send it to the player for import. After that, the player can play the game with the option selected.
EDIT3
Finally we found the intermediate certificate is right on the nginx side,but on the server side, the ca is missing. After add it, the websocket could work. And When I asked same question on another forum v2ex,I found a good way to test if the certificate chain is complete. you can visit the site and change the domain and port with your site.
https://cert.catbox.io/api/v1/queryChain?domain=s41001-ad-tanwan.zlgl.17tanwan.com&port=8085
If your server is correct, you will find the server side certificate and the intermediate certificate.If you can't find the intermediate certicate, you need to check your server config.

Answered 2020-Nov-24 at 05:25Your server https://s41001-ad-tanwan.zlgl.17tanwan.com/ provides only the last certificate in the chain, the actual certificate of the server.
This certificate is signed by the intermediate certificate from "RapidSSL TLS DV RSA Mixed SHA256 2020 CA-1" that is valid since 2020-07-16. If the clients have not updated their browsers/operating systems for some time, they don't have this intermediate certificate, and they report this as an invalid certification authority.
Put the intermediate certificate to the certificate file, and it should fix the problem, since the intermediate certificate is signed by the DigiCert root certificate, that is in the game since 2006. Everyone has it.
You run nginx, right? The ssl_certificate
instruction in nginx accepts files with certificate chains. This file should have the server certificate first, then the intermediate certificate.

Install v2ex
You can use v2ex like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
