However, it is possible that there's something wrong on your end and we'll work through those possibilities below.

1. Try loading the URL again by pressing F5 on your keyboard, or by clicking the refresh/reload button.
   
   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.
2. Start a new browser session by closing all open browser windows and then opening a new one. Then try opening the webpage again.
   
   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.
3. Clear your browser's cache. Outdated or corrupted files that are being stored by your browser could be causing 502 Bad Gateway issues.
   
   Removing those cached files and trying the page again will solve the problem if this is the cause.
4. Delete your browser's cookies. For similar reasons as mentioned above with cached files, clearing stored cookies could fix a 502 error.
   
   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.
5. Start your browser in Safe Mode. Running a browser in Safe Mode means to run it with default settings and without add-ons or extensions, including toolbars.
   
   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."
6. Try another browser. Popular browsers include Firefox, Chrome, Internet Explorer, andSafari, among others.
   
   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.
7. Download Software Update 1 for Microsoft Forefront Threat Management Gateway (TMG) 2010 Service Pack 1 if you have MS Forefront TMG SP1 installed and receive a Error Code: 502 Proxy Error. The network logon failed. (1790) or similar message when accessing a web page.
   
   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.
8. Restart your computer. Some temporary issues with your computer and how it's connecting to your network could be causing 502 errors, especially if you're seeing the error on more than one website. In these cases, a restart would help.
9. Restart your networking equipment. Issues with your modem, router, switches, or other networking devices could be causing 502 Bad Gateway or other 502 errors. A simple restart of these devices could help.
   
   Tip: The order you turn off these devices isn't particularly important, but be sure to turn them back on from the outside in. In other words, turn on the outermost hardware on the network first (usually your modem), followed by the device it's connected to (usually your router). Next would be any switch or other device between the router and your computer.
10. Change your DNS servers, either on your router or on your computer or device. Some Bad Gateway errors are caused by temporary issues with DNS servers.
    
    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.
11. Contacting the website directly might also be a good idea. Chances are, assuming they're at fault, the website administrators are already working on correcting the cause of the 502 Bad Gateway error but feel free to let them know about it.
    
    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 #cnndown or #instagramdown.
12. Contact your Internet Service Provider. If your browser, computer, and network is working, and the website reports that the page or site is working for them, the 502 Bad Gateway issue could be caused by a network issue that your ISP is responsible for.
    
    Tip: See How To Talk To Tech Support for tips on talking to your ISP about this problem.
13. Come back later. At this point in your troubleshooting, the 502 Bad Gateway error message is almost certainly an issue with either your ISP or with the web site's network - one of the two parties may have even confirmed that for you if you contacted them directly.
    
    Either way, you're not the only one with seeing the 502 error and you'll need to wait until the problem is solved for you.

Hi,

The error you are getting, HTTP Error: 502 Bad Gateway, is not a problem that you are able to fix.

The error relates to one of two things:

1) The site you are trying to access has a problem with it's server and you will get the same error message from any device that trys to access the site.

2) Your network carrier is experiencing network difficulties/equipment failure and needs to repair the fault.

The error may already have been resolved. To check this, restart your phone to clear the cache and try to access the internet again.

Shut down the printer, check whether the printer has peripheral devices such as a stabilizing power supply, and disconnect them.After five minutes, restart the printer to see whether the fault corrects itself. If the fault persists, the heating component may be faulty and the printer will need to be repaired.

Thanks for using FixYa.

Try cleaning the slider bar  upon which the ink cartridge slides abck and forth -- NOT THE TAPE- the slider bar assembly it self .. It worked for me .
