My company website is hosted on Simply Transit, running WP.
It works perfectly from anywhere outside my company LAN. Inside the LAN, trying to connect to mycompany.com would result an
ERR_CONNECTION_TIMED_OUT
Inside the LAN I can tracert the site and it resolves correctly. Using a web proxy I can access the site.
I tried to flush dns and disabling firewall on LM, disabling the most 'suspected' WP plugins on server with no results.
