After finished building, I go to web: ..../admin/login and get error 502 Bad Gateway. I get an error in nginx
2014/06/18 16:19:11 [error] 3263#0: *7 connect() failed (111: Connection refused) while connecting to upstream, client: 172.18.51.34, server:
sip.freepybx.org, request: "GET /admin/login HTTP/1.1", upstream: "
http://127.0.0.1:2088/admin/login", host: "172.18.51.248"
Can anyone help me to fix?
