It is best to try clearing cookies if clearing cache does not solve the problem. You can also delete specific cookies for each site instead of deleting all of them. It is better to delete all the cookies but you can try deleting specific cookies if that solves the problem.
5. Try Safe Mode:
You can start the browser in Safe Mode. This will disable the extensions and run the browser with default settings. Now, you can check if the error is occurring. If it is solved, then the problem is definitely with one of the extensions. Select each extension and try reloading the webpage. Search which extension is causing the error and then take action.
6. Try a Different Browser:
If all the above steps do not work, then try changing the browser itself. If you are using Google Chrome then try switching to Firefox, Safari or Microsoft Edge etc. If this solves the problem, then you can conclude that the problem was with your earlier browser. You can try reinstalling that browser and see if the problem is solved. Trying a different browser is definitely a good idea.
7. Restart Your Computer:
There can be some temporary problem with the system you are using, the way it connects to the network could cause the 502 Bad Gateway error. Restarting your computer will reset the situation and might fix the error if it is associated with the system.
8. Restart your Networking Gear:
Check your modem, router, switches and other networking devices. These might be causing the error. Restarting them might solve the problem.
9. Change DNS Server:
DNS servers are assigned by ISPs by default. These work most of the time. But you can try changing them on your device, router or computer. You can use public DNS servers such as the ones provided by Google. A problem with DNS can cause a 502 error.
10. Check Plugins at your WordPress site:
Sometimes a bad code in a plugin can interfere with the functioning of your website. This can cause a 502 error. To resolve this, simply go to the dashboard of your website. Select Bulk Actions.

11. Contact your Host:
The 502 error may be on the server-side. Contact the web host or administrator and let them know about the problem you are facing. In shared hosting, scripts like kill scripts can cause errors while accessing the website as the resources are shared.
12. Contact Your Internet Service Provider
In the rare instance when there is no problem with your browser, computer, networking equipment, or website and if you are still getting the 502 error, then it might be a network issue caused by your ISP.
After trying all these steps, you can only hope that the issue gets solved by your ISP or website’s network. The only thing that is remaining to be done is to wait. If you have contacted your ISP and website administrator, they will let you know when the issue gets resolved at their end.
