Hello, I'm having this same problem with a website I created and am wondering if you could help me. I can connect to the website using my phone and my home network, but am unable to get on at my office. The problem happens across all of the computers at my office so I'm assuming that the problem is my server. I reset my router and modem but that did not solve the problem. I ran the tests you stated above and here are my results.
