Proxy error on remote login

I have the RubyStack + Redmine module running on an XP server. All functions fine however when I login each morning from my client PC I always get a Proxy error the first time I access http://server/redmine. Sometimes it clears if I refresh however sometimes I have to go to the server and access redmine locally before I can successfully access it from the remote PC.

The server runs continuously overnight. The problem only ever occurs when I login from my PC which has been off overnight. Any thoughts? Looking at another similar problem post it talked about accessing the mongrels on the local machine. I can only access 3001 and I can only see 1 mongrel service. Is this the problem? If so where do I look to fix it?

Hi,

I think that the cause of this error could be the Windows Firewall. Other users have a firewall rule for Apache so the firewall can not manage the requests. Could you check this?

Other related cause could be the service startup order. Usually Apache starts after mongrel services startup, but sometimes Mongrel service takes some time before starting. In this case Apache is started before the mongrel service is running. Could you try to reboot your Apache server (rubystackApache service) and check if this is the problem?

Cheers.

Hi,

Thanks for the swift response.

No Firewall enabled on the server so that rules that out.

As for the service startup order – like I say the server is not shut down, so I am working with Redmine OK on the client PC all day, shut down the client, come in next day and the problem occurs. The server has not been restarted. Its just the time gap between uses. The only thing that happens to the server overnight is that it is backed up with Yosamite Tapeware.

Aha ok, could you see any error in the Apache log that could help us to find any clue about this error?

OK, heres the error.log showing the prob yesterday (Thur) and today, followed by the restarts I have done today.

I’ve been struggling with this issue for some time when I got a phone call on my cell phone !
I disconnected the mobile from USB and RedMine started working !!!!!
Problem was with my Windows Mobile ActiveSync set to synchronize with Outlook which was was interfering with the proxy server.
This may not be the issue for everybody, but hopefully it helps.
