Chess.com app not working

As of recently whenever I opened my chess.com app during school (at lunch etc.), I would be automatically logged out and greeted with a message that says; "could not connect to server" and would also be placed into offline mode. A similar thing happens when I try to use the chess.com website where I cannot load the site and receive a message that says; "Safari cannot open the page because it could not connect with the server. Furthermore there are various parts of the building where I am having no issue connecting to my account, and I have no trouble using the app outside of school. All of my classmates have no problem using the app in school and I use an iPhone with a Google account In case that helps (my chess.com app and phone are fully updated)
