I had a fully working Drupal site and had some problems with uploading files on a specific page. So I started looking closely at the code and noticed some oddities (basically a lot of random characters). I removed the code and everything seemed to be fine. The code had to do with the images on the page. Then all of a sudden I started receiving a "page cannot be displayed" error, and was not able to view the site anymore.
I had someone else look at the server and they were able to connect just fine. To be on the safe side, they rebuilt the page. I tried again, and still couldn't see the website.
I then tried to attempt the connection through another network I manage via VPN. Coming at it from the other network, the page loads. I've tried Firefox, Chrome, Safari, all with the same result. I tried clearing the cache, reset settings, delete and reinstall. I've restarted my router. I'm out of ideas. This has been super frustrating. Thanks for any help.
Update: I talked to the person hosting this and they mentioned they run something called Liquid Web. I guess it bans your IP if it thinks you're doing something bad. All I did was modify a page it banned me.
