While you are browsing any sites or pages on the Internet, when accessing various sites, a "502 error" message may appear on the screen of your monitor. In this case, you cannot open the pages of sites, and you do not have the opportunity to view and explore the resources of this website. As a rule, such an error occurs due to the fact that problems are detected in the operation of servers, mainly a DNS, proxy or hosting server on which the site is currently inaccessible.
The expression "error 502 bad gateway" can be translated as "invalid gateway". This will mean that the browser (Internet browser) on your computer, when requesting some information from the website, received an unacceptable response from another server (DNS or proxy server). This is reported to the user when the message “502 error” is displayed on the screen.
Most Internet users have encountered this error many times, but for some it may be the first time. What to do when the message "error 502" appeared on your computer screen? First of all, you need to check if you have access to the Internet at all. To do this, type in the browser the address of another site, whichis guaranteed to work at the moment, because, for example, corporate access to the Internet is carried out through a proxy server, and not immediately through a modem connected to or built into your computer. If in the latter case the error is recognized in more detail, then when accessing the Internet via a local network, the system does not have the ability to check the error. In this regard, the user has no choice but to find out the reasons for its appearance by indirect methods.
If you have access to the Internet, but when you try again to request a page from the required site, the message "error 502" still pops up, then in this case you should try to delete cookies for this site or all those in your browser.
To do this, you can do the following:
- for Internet Explorer versions 7+: in the menu, go to "Tools", then select "Internet Options", click on the "Delete" button, and then on the "Delete cookies" button;
- for earlier versions of Internet Explorer: go to "Tools menu", look for "Internet option" and click "Delete cookies";
- for Firefox: go to "Tools", look for "Settings", select "Cookies" and click on "Clear cookies";
- for Opera: go to "Tools", select "Delete personal data" and tick the necessary options;
- for Google Chrome: go to "Tools", click on "History", click on "Clear History" and then on "Clear Cookies".
During normal, normal operation, such an error appears very rarely, only in cases of restarting the web servers. If it is noted for more than thirty seconds, then you should try clearing the browser cache, cookies, and restarting the browser itself
If after the steps taken to clear cookies, the message “error 502” still appears on the screen, this indicates that everything is in order with your computer and network, and most likely there was simply a problem with the server. In this case, you should wait a bit until the administrators resolve these issues, and then try again.
