I have 3 virtual servers on the system and I just noticed that I can’t access port 20000 on one of the 3 virtual servers. The browser just simply return the following error:
This site can’t be reached
**example.com** took too long to respond.
@vander.host The other virtual servers (domains) that are hosted in the server all share the same ip address and they are working fine so I’m not sure what is causing just one of the domains to not work even though roundcube is working fine for that particular server where usermin isn’t working.
