I'll summarize my problem as concisely as possible. I'm taking an online real estate course that requires, by law, that I spend a certain amount of time in each unit. For 2.5 months, the timer on the website worked perfectly, tracking the exact amount of time I'd been logged in to each unit. It worked perfectly when accessed from my home Mac (over WiFi), my iPhone (over LTE and home WiFi), my iPad (over home WiFi), and from my work PC (over ethernet). However, 5 days ago, the timer stopped counting, and no longer works from any device on any network that previously worked for me. I called Tech Support, but they were little help, suggesting I find a stronger internet connection.
Meanwhile, I've asked family and friends to log in, and they all see the timer working perfectly. Nothing has changed with my internet connections, at home or at work, and they're as strong as they've always been.
Because "new" devices seem to have no issues, my working theory is that my home network and/or devices have been "blacklisted" by their servers for some reason, possibly because of too many timed out sessions (I did tend to not log out).
So in short, to prove or disprove my theory, I'd like to be able gain a whole new identity, such that when I access the website, it believes I'm a new device on a new connection from which the website has never been accessed before. What would that entail? I have Verizon FIOS with their router using factory defaults. My home computer is an iMac running OS X El Capitan. I'm happy to mess with its settings.
I have 9 days remaining to complete 10 units worth of work, so I'm desperate to find a solution. Technical support is "working the issue", but I'm not confident they'll get to the bottom of it. If I don't finish the course material, they cannot give me an extension or refund me my money. Any support from the community would be greatly appreciated.
