Hello Nancy,
Unfortunately, a 502 Error isn't something we can help with - it's usually an infrastructure issue!
Please have a look at the following steps, hopefully these will help you resolve this problem

The 502 Bad Gateway error is often a network error between servers on the internet, meaning the problem wouldn't be with your computer or internet connection.
However, it is possible that there's something wrong on your end, here are some fixes to try:
While the 502 Bad Gateway error is usually indicating a networking error outside of your control, it could be extremely temporary. Trying the page again will often be successful.
It's possible that the 502 error you received was due to an issue on your computer that occurred sometime during this use of your browser. A simple restart of the browser program itself could solve the problem.
Removing those cached files and trying the page again will solve the problem if this is the cause.
Note: If you'd rather not clear all of your cookies, you could first try removing only those cookies related to the site you're getting the 502 error on. It's best to remove them all but it won't hurt to try the clearly applicable one(s) first.
If the 502 error no longer appears when running your browser in Safe Mode, you know that some browser extension or setting is the cause of the problem. Return your browser settings to default and/or selectively disable browser extensions to find the root cause and permanently fix the problem.
Note: A browser's Safe Mode is similar in idea to the Safe Mode in Windows but it is not the same thing. You do not need to start Windows in Safe Mode to run any browser in its particular "Safe Mode."
If an alternative browser doesn't produce a 502 Bad Gateway error, you now know that your original browser is the source of the problem. Assuming you've followed the above troubleshooting advice, now would be the time to reinstall your browser and see if that corrects the problem.
Important: This is not a common solution to 502 Proxy Error messages and only applies in this particular situation. Forefront TMG 2010 is a business software package and you would know if you have it installed.
Tip: The order you turn off these devices isn't particularly important, but be sure to turn them back on from the outside in. Check out that link above for more detailed help on restarting your equipment if you need it.
Note: Unless you've previously changed them, the DNS servers you have configured right now are probably the ones automatically assigned by your ISP. Fortunately, a number of other DNS servers are available for your use that you can choose from. See my Free & Public DNS Servers list for your options.
See my Website Contact Information page for a list of contacts for popular websites. Most websites have social networking accounts they use to help support their services. Some even have telephone and email contacts.
Tip: If you suspect that a website is down for everyone, especially a popular one, checking Twitter for chatter about the outage is often very helpful. The best way to do this is to search for #websitedown on Twitter, as in #cnndownor #instagramdown.
Tip: See How To Talk To Tech Support for tips on talking to your ISP about this problem.
Either way, you're not the only one seeing the 502 error and so you'll need to wait until the problem is solved for you.
