Hello, I’ve just run ./launcher rebuild app with no apparent errors. But when I try to open the site, I get a 502 error. The nginx error log (shared/standalone/log/var-log/nginx/error.log) shows: 2020/08/12 05:47:43 [error] 653#653: *7 connect() failed (111: Connection refused) while connecting t…

Wooo, looking at the rails logs I found that the unicorn log was huge, complaining about some permission errors. I deleted rm -rf tmp/cache/bootsnap-compile-cache/, and now I see the congratulations screen!!! Thank you friends. I’ll play with this a little more before deciding to recreate it in an …

It shows 502 initially as the services inside the container are starting up. It should go away within 30 seconds. If it doesn’t it is possible that your server’s CPU is under extreme load and it is causing slowdown.

And is that the cause for the 502 error? Or without an SSD should I see the website working, but very slow?

Using a traditional hard drive versus an SSD drive should not cause a 502 error. That’s not really plausible, as your question indicates @elopio . Here is a little writeup which might be helpful: [画像] How to Solve 502 Bad Gateway Issues? - KeyCDN Support Having issues with a 502 Bad Ga…
