I’ve just done an in-place upgrade from version 6 to version 10 and my /admin/ redirect has stopped working. I’m getting an immediate 502 error.
I’ve tried the advice from other topics on this issue (restarting php5-fpm, etc) and it has had no effect. From my limited understanding, nginx is being used as a proxy to provide the admin panel but whatever is serving the admin panel is down.
The only error I can find is in /var/log/nginx/error.log, reproduced below;
2015/06/21 16:35:11 [error] 3259#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: box.xxx.xxx, request: “GET /admin HTTP/1.1”, upstream: “http://127.0.0.1:10222/”, host: “box.xxx.xxx”
Nothing from PHP in syslog or anywhere else that I can find. Anyone have any ideas?
