Subscription Server Error occasionally

[EnriqueR]

A few days ago one of my subscriptions return the following error while loading the page: 504 Gateway Time-out OR Internal Server Error. This only happens occasionally. I opened the proxy_error_log file with the following messages appear:
2015/07/29 16:35:53 [error] 16125#0: *10463545 upstream timed out (110: Connection timed out) while reading response header from upstream, client: x.x.x.x, server: domain.com, request: "GET / HTTP/1.1"...
2015/07/29 16:36:31 [error] 16125#0: *10463545 upstream prematurely closed connection while reading response header from upstream, client: x.x.x.x, server: domain.com, request: "GET /favicon.ico HTTP/1.1", ...

Only happens with that subscription. The rest work perfectly. You know how to fix it?

Try to reconfigure webserver setting for this domain at least with

# /usr/local/psa/admin/bin/httpdmng --reconfigure-domain domain.com

Thank you. I'll try with this command to see if it clears.

Unfortunately it has failed again, so this change has not solved it. Can you think of any way to tell what is going wrong?
