Title: Qythyx: Library Server problem
Post by: Qythyx on August 30, 2011, 10:32:57 pm

I've been having persistent problems with accessing my Library Server for a few months now, but never bothered to mention it before. I don't know exactly when it started.

The problem is that when I first start MC on my client PC it says that it fails to load the library from the server. If I retry loading enough times it eventually works, but this sometimes takes 5, 10, or even more retries.

Is there anything I can do to help diagnose this?

Here are the portions of the log I guess are relevant:

You use port 80 for your library server? Could be something competing for that port, maybe you should try changing it.

Unfortunately I can't, other ports are firewalled from my office.

Also, once the library loads, I never have problems. All music and album art loads just fine.

It's strange that it's taking a full second to respond to http://<my_secret_url>:80/MCWS/v1/Alive.  That should be really fast.

What if you test the URLs in a browser?

This should return a ZIP of the library:
http://<my_secret_url>:80/MCWS/v1/Library/Get

We use a 60 second timeout for that call, so I don't think it's a timeout issue.

Thanks.
