HTTPS access issue using DigiCert free SSL certificate

Since my server’s 80 port was disabled, so I can’t use LetsEncrypt for HTTPS. I buy a free SSL certificate, and configure it in “/etc/gitlab/gitlab.rb”, like below
I can’t access it through https://domain name, but https://ip works.
Can someone help me on this?

The SSL cert was bought for and I already resolved it to the external IP.
Now, I can access gitlab via https://ip but not
In linux, when I execute curl it’s okay, but when I input it in windows brower, it pops up “ERR_SSL_PROTOCOL_ERROR” error and gitlab can’t be opened.


Just to double check, after making those changes you did ran sudo gitlab-ctl reconfigure ?

Have you checked the logs to see if you get any errors there that might help troubleshooting this issue?
