Cpanel/whm not working

[retechpro]

Recently i faced very strange issue. My litespeed license was expired and server was working on apache. I renew the license and moved to litespeed then my all sites on server and whm not working. Whm showing took too long to respond.
Sites showing : this site can’t be reached.

Then i moved from litespeed to apache using ssh. Because only ssh is working still did not find a solution.
update cpanel still not resolved.
Uninstall litespeed and install. Did not resolved.

what the possible causes of this issue.

Hey there! I would not expect a LiteSpeed license change to affect the cPanel & WHM interface. We don't use the same Apache server that handles your websites to serve cPanel content, so the two are not related. It sounds like there could be multiple issues with the machine happening at the same time.

Do you see anything helpful in the cPanel error log (/usr/local/cpanel/logs/error_log) when you try and access the WHM interface?
