Title: Bad gateway Error code 502 Last modified: September 12, 2022 --- # Bad gateway Error code 502 * Resolved [alaid](https://wordpress.org/support/users/alaid/) * (@alaid) * [3 years, 8 months ago](https://wordpress.org/support/topic/bad-gateway-error-code-502/) * Hi, * An excellent plugin, congratulations. I have been testing the plugin for 2 weeks on several sites and so far it has worked fine, but today a Bad gateway Error code 502 error started appearing in the browser of all users who visit the site, however when entering with a browser different can be entered normally, until that point I thought it was the browser cache, but it also happens to other visitors, once I proceeded to enter from the Paneld and WordPress Administration in Pages or Entries the error appeared again, from any browser that I did the test and deleting the cache did not solve the issue, when deactivating Headers Security Advanced & HSTS WP plugin everything works perfectly. * I like this plugin, in the other sites until now it works perfectly, but in this one, which is a newspaper and has more than 50,000 articles, it presents me with this error. * What do you think it could be and how to fix it? * Thanks.
