Timeout when using proxy_pass

[zarza]

We're getting this in our logs:
[ngx_pagespeed 1.9.32.6-7321] Serf status 20014(Internal error) polling for 1 threaded fetches for 0.05 seconds
2015/09/24 16:10:00 [error] 19762#0: [ngx_pagespeed 1.9.32.6-7321] URL https://... (connecting to:127.0.0.1:7779) active for 1 ms

How can we increase those 0.05 seconds?

We already tried by our own but looks like we're missing something.

Thank you for your time.

Could you try adding:

pagespeed ListOutstandingUrlsOnError on; 

to your config to help debug this?

(It's not complaining about a 0.05 timeout; something else went wrong.)

Could you also paste the pagespeed directives you have in your config? I'm especially interested in any MapOriginDomain or MapRewriteDomain lines.

This earlier thread looks relevant: https://groups.google.com/forum/#!topic/ngx-pagespeed-discuss/EAgku-2C-o8

Hi jeffkaufman, thank you for your time and for your great work.

ListOutstandingUrlsOnError is already on.

Currently we're not using MapOriginDomain or MapRewriteDomain, should we?

It looks to me like pagespeed is trying to fetch using https via 127.0.0.1:7779:

2015/09/24 16:10:00 [error] 19762#0: [ngx_pagespeed 1.9.32.6-7321] URL https://... (connecting to:127.0.0.1:7779) active for 1 ms

while the server configuration you just posted doesn't have https enabled:

     ssl off;

Is there are server in front of ngx_pagespeed that terminates SSL?

• If so, you could configure PageSpeed to fetch via the server that terminates SSL by applying a MapOriginDomain configuration line:
  https://developers.google.com/speed/pagespeed/module/domains#mapping_origin
• Alternatively, you could tell PageSpeed to use http instead of https via the loopback address that way as well.

Thank you for your update Oschaaf. After some changes we got it working. Thank you again!
