      Meanwhile I've reverted to my previously installed version (1.12.0) and everything is fine again. Completely lost here.

    • RE: 502 for post pages, error reading status line from remote server localhost:4567

      There are no errors in nodebb's log file.

      If I change the config.json url to http://<myip>:4567 and try to load that in my browser, I get the main page again, but now 403s and this in the console:

      You are accessing the forum from an unknown origin. This will likely result in websockets failing to connect. 
      To fix this, set the `"url"` value in `config.json` to the URL at which you access the site. 
      

      That's weird, because for that test, that URL is set to the one I'm accessing it by?!

    • 502 for post pages, error reading status line from remote server localhost:4567

      After an upgrade to 1.13.2 (I think from 1.12.x), I cannot access any forum posts anymore. I reconfigered my apache conf as per the docs - the Websocket passthrough rules definitely weren't required with the old version, but something's not right. I can load the forum main pages, but as soon as I try to load a post page, after some delay, I get a 502 in the browser and this in my apache error log:

      [Thu Feb 27 21:11:21.672963 2020] [proxy_http:error] [pid 5133] (20014)Internal error (specific information not available): [client x.x.x.x:62276] AH01102: error reading status line from remote server localhost:4567

      I'm running Apache/2.4.7 on Ubuntu, there's another (Java based) Websocket server running on another v-host on that box which works ok.

      Here's the full conf for the forum v-host:
