I am facing the same issue & figured out the Problem, it’s because of SSL is not installed on the Origin Server but you have enabled Full SSL on CloudFlare. Just change the CF SSL to Flexible, hope it will be fine.

I figured out the Problem, It's SSL issue, when I enabled Full SSL on CloudFlare, It's returning to 502 or 520 Error page, because SSL is not installed on Origin Sever.

And the Fact is, I have installed Let’s Encrypt SSL using CyberPanel, I also reissued 2 times to fix the Issue but not solved because CyberPanel actually not installing SSL, even it shows Success Message. I verified it.

OLS server is updated:


LiteSpeed/1.4.38 Open

How to fix this SSL Installation Bugs? Or install Let’s Encrypt SSL for that site/domain manually?

Two days ago, two of my ip’s got blocked in China. Can’t ssh into it. China is using AI now to censor now. Ss fixed. Minor disturbance.

I have the same issue can anyone please help?
