Sorry, I mixed up different forums, and forgot to switch between languages... Now re-posting in English. Admins, please delete my errorneuos posts.
Very often I'm getting the following messages while trying to read some of recently posted topics:
Quote:
502 Bad Gateway
nginx

I did not touch any networking issue since long time. Kindly give me any idea, why this happens OCCASIONALLY, and with NEW TOPICS only - ???

After some extra investigation I've found that "502 BAD GATEWAY" occurs regularly ONLY when using Chrome under Mac OS; it doesn't happen with other browsers/OS tested so far. Right now I'm able to read/post all topics with Safari/MacOS, or Chrome/Android, for example.

This error did not happen just a month ago, with all the same settings and system. I'd highly appreciate any idea: what to check, or to test for fixing this issue.

Thank all in advance.

I am regularly using chrome with high sierra and everything works smoothly

the most frequent suggestion people get when something odd happens
is to clear the browser caches

I think I've occasionally seen Bad Gateway with Windoze browsers. Earlier today (US Eastern time) I saw site not found for ibmmainframeforum.com, the sister site for this forum. I always thought the two sites were hosted on the same system, so this struct as sort of strange. Whatever the underlying problem, was was quickly corrected.

Thanks to all.

No luck. It works fine everywhere except Chrome/MacOS. Neither clear cookies, nor clear browser caches, nor full shutdown and restart helps...

On Mac - High Sierra, version 10.13.4 (17E199) - old topics work fine, too; almost none of new topics can be viewed.
Other forums with the same engine work fine.

The only solution so far: I use Android on my tablet when out of home, and use Safari/MacOS at home, to access exclusively Mainframe Forum.

Update to previous discussion.

After my vacation, the 502 BAD GATEWAY problem has disappeared by itself. Now it's working again, with any browser, any OS, and any topic.

Before that, I tried to consult with other network experts I know, but none of them was able to clarify possible reasons for this strange behavior...
