Scan Media Library Failed

[ComputerNerd 0]

Hello MB3 Community, I need your help.  I am new to the MB3.  I built my first HTPC a few weeks ago and installed MB3 as it was highly recommended by a friend.  Have to say that so far, I love it.  Besides the minor known issue with the CPU getting maxed out because of all the streaming to my kids iPads, everything else has been going great.  That is until the recent MB3 server update.

 

After the server update, it appears that MB3 server is getting stuck doing a library scan.  I even tried completely uninstalling MB3 and reinstalling, no such luck.  When I am on the MB3 server dashboard, I keep seeing "Scan media library failed.  Object reference not set to an instance of an object".  When I review the logs, the only errors I see are the same one (see below).  I am running MB3 server Win7 Ultimate x64.  I appears that MB3 server is reaching out to my router (Asus RT-AC66R) and detecting that it supports UPNP?  I can restart the MB3 service and the library scan will continue to reach a little further before it dies again.  I assume I can keep restarting until the library scan is complete; however, that's not a fun solution.  Any suggestions you might have would be greatly appreciated.

 

Respectfully,

Ryan

 

Here is the error I keep seeing in the logs...

They will most likely need to see a complete log file. There is nothing above related to the Scan Library task.

 

You can probably clear the error above by turning off UPNP under Advanced -> HTTP Server.

[Luke 42078]

that's coincidental. it has nothing to do with the library scan.

I just turned off the UPNP option and restarted the MB3 server, now bam, it's working like a champ!  It's now scanning and downloading the library metadata without stopping after a brief period.  So far it's up to 34%, the highest I have seen yet since I reinstalled in attempt to fix the problem.

 

I have a wireless USB3 / 802.11AC network card (Linksys WUSB6300) connect to an Asus RT-AC66R router I assume wasn't playing well with the UPNP turned on.  I will keep on monitoring it and let you know how this story ends...I hope it has a happy ending.

 

Maybe the problem is with the wireless losing connection, who knows?  /shrug
