111: connection refused while connecting to upstream [Solved]

[vanderheyde]

Hi,

when browsing to any client domain (vestacp interface works fine), i receive a 500 internal server error.

From /var/log/apache/domain/xxx.error.log, i get this:

Code: Select all

2017/12/08 16:44:04 [error] 1651#1651: *38 connect() failed (111: Connection refused) while connecting to upstream, c lient: xx.xx.xx.xx, server: xxx.com, request: "GET / HTTP/1.1", upstream: "http://yy.yy.yy.yy:8080/", host: "xxx.com", referrer: "http://xxx.com/"

nginx does not return any errors, neither does php5-fpm.

I'm at a loss. I can't find any other error to troubleshoot this issue, and I'm unsure of what to make of the one I have.

Any and all help would be appreciated :)

Found the issue:

/etc/apache2/conf.d/yy.yy.yy.yy.conf did not contain "listen yy.yy.yy.yy:8080"

Also having the same problem, updated the server at some point then restarted later on and all local websites are doing this.
