A 404 error happens when the server can't find the file. So this issue just occurs when the internet is slow? If everyone does not experience this issue, it might be tough to pin point the issue via our forums. Is everyone using the same internet connection? Does this issue just occur with specific devices? I suggest giving our hosting team a call so they can look further into this. They can be reached by dialing 480-463-8824.
