can you please tell me if you got LiteSpeed License with CyberPanel bundle or not?
and also if you are using Cloudflare

hello, yes im using Cloudflare . for the LiteSpeed License , i just got to LiteSpeed Web Server Pricing - LiteSpeed Technologies
and bought the free starter package .

The free starter license only supports 1 domain and unlimited subdomains. You may have added multiple domains in your cyberpanel and hence its not working.

no om only working with one domain
