If the site was working in other browsers at the same time, I’d first clear Opera’s cache, disable any VPN/proxy or ad-blocking extensions temporarily, and try a private window. It may also be worth checking Opera’s DNS settings.

If the error appeared across multiple browsers, the problem was more likely related to the hosting server, reverse proxy, CDN, or a temporary outage. Checking the server/error logs would usually reveal the cause.

I’ve run into similar temporary gateway issues while working on a website, and in most cases the browser itself wasn’t the actual problem.

The other day, I was trying to open my website - on the Opera browser, and it was set as the default homepage. Turns out it was showing 502. Why was this happening

Your site is returning a 403 Forbidden error on my end not a 503. Could you please check it again? I think the issue might be related to the wp-config.php file.

I also have the same question. I'm seeing a similar 502 Bad Gateway error when trying to access a site through Opera, while other browsers sometimes load it normally. I'm not sure whether the problem is related to Opera itself, the site's server, or something with the connection.

I've already tried refreshing the page and restarting the browser, but the issue still appears intermittently. If anyone knows what usually causes a 502 error specifically in Opera or has found a reliable way to troubleshoot it, I'd appreciate any suggestions.

• Open a private window and test the website on it.

• Disable AdBlocker / VPN.

• Clear cache.
