When I downgraded from liteSpeed ​​Enterprise to Open LiteSpeed
I follow: Upgrading/Downgrading OpenLiteSpeed ​​– OpenLiteSpeed

But when we try to access the website’s it doesn’t work and shows the server is down. But when we access CyberPanel via the admin console it works perfectly. I am unable to find out if OpenLiteSpeed is working for CyberPanel why isn’t it working for websites.

Run the following and post screenshot

$ service lsws reload && systemctl status lsws

If you are using Cloudflare for your websites disable it temporarily

Yes. I turned it off but the website still doesn’t work.

Post a screenshot of what you see when you visit one of your websites on the cyberpanel server

What error do you get on Safari ?

Can not connect to server

Did you try to disable proxy, vpn or use one instead ?
