I've been exploring the network aspects of MC. I've also set up a VPN, so have needed to sort through some MC and router configuration to re-establish required functionality. As a result, on the PC involved the Gizmo TCP Port is 52181.
After inserting the following into a web browser address bar:
localhost:52181
I'm directed to the Library Server page.
The Hang occurred when the link to "Library Server" was executed. The .zip file of all the standard files can be found at:
https://www.dropbox.com/s/7iv11g4bspkvcks/201403Mar28%20Hang.zipDuring the Hang, Gizmo allowed Play to This Location but not Play to Player.
In addition, I believe that there is a fault with the Library Server page. The link referred to above shows the following text for that example:
mc19://MCWS/v1/Library/Connect?URL=m01p://localhost:52181
This command goes nowhere and brings up an error message, "Error Loading Library - There was a problem loading the library 'Connected Library'".
If I manually insert the following, then the system works sensibly:
mc19://MCWS/v1/Library/Connect?URL=http://localhost:52181
Isolated case? Late night keyboard entry fuddle during coding?
