In the process of attempting to visit a site, I received an error message of bad gateway error code 502. I do not know whether it is my internet or the site itself. What, do you think, is the real cause of this mistake, and what can I do to correct it, on my part?
A 502 Bad Gateway error is typically an issue in the server of the webhosting and not your internet. It occurs when one server receives a faulty reaction of the other one. On your side, you can try:
Refresh the page
Clear your browser cache
Restart your router
Use one more browser or device.
In the event it occurs, the site itself might be malfunctioning and you will have to wait until they correct the malfunction.
