I saw that.  Thanks.

It looks like forwarding on the router isn't successful.  Is it set up correctly?

Remove the audio files from MC's library again.
Then create a smartlist by right-clicking on Smartlists in the tree and do Add Smartlist.
Give the smart list the name
Bad or Removed
Click the x under Rules to delete the default rule
Go down to Modify Results and select
Limit database to
in the next field check
Removed
and
Bad
Click OK

You should see the files you just deleted in that smartlist (and perhaps others).
At any rate select the ones you just removed right-click and do delete "remove from media library"

That will removed the cached data.
If you add the cue now you should get whatever new data MC can read from the new cue.

@Jim:
LAN works.
WAN does not.

Our Android app called Bingo SSDP will find Media Server instances running on the LAN and can connect to them.

Double check the IP address of the server.

Which antivirus do you have?

You can try Mongoose web server:
- download from here: https://mongoose.ws/binary/
- forward TCP port 8000 from your router to your PC
- run Mongoose
- try to access it: LAN = http://192.168.1.68:8000 , WAN = http://99.8.xx.xx:8000
   Both links should show the contents of the Mongoose folder.

Uninstall any antivirus other than Windows Defender.  Configure it.

Are you sure JRiver's Media Network is running?   You could move it to another port.  52150, for example.

Firewalls are also a possible problem. 

Read Network Access on the wiki.

At this point, unless you have some other security software installed, the most likely cause is still the router.

Is there some utility I can run that is independent of MC that will determine if port forwarding is working correctly?  My understanding is that if the traffic makes it to the studyPC2 then MC will know what to do with it.  Something as simple as ping?

AT&T claims that there is no firewall stopping network traffic, but who knows if their techs really understand what's going on.
 

I'm not aware of any additional security software that might be installed, but the anti-virus providers really like to install their stuff without you knowing so there may be something, but I'm not seeing anything suspicious in the process list, although there are a lot of things running that I don't know what they are.

If you pick backup from the file menu it asks you to specify a path. If you run an automatic, the path is in options.

Try other paths.

Added a file to Library and, per usual, attempted Library Backup which failed in several attempts.
Not a problem previously.
I do not even know where the Backups are stored.

I went through this a while ago. The problem was that Comcast has an Advanced Security feature which blocked the port forwarding. Once I turned that off, everything worked. Are there any security settings on your Gateway that you can turn off as a test? Grasping at straws.

There's a section on the router UI for NAT/Gaming that turns on port forwarding, so one would expect that to turn on port forwarding. There's the firewall advanced tab which reports that all these are off:

Drop incoming ICMP Echo requests to LAN   
Drop incoming ICMP Echo requests to Device LAN Address   
Drop incoming ICMP Echo requests to Device WAN Address   
Reflexive ACL    
ESP ALG    
SIP ALG

I don't think I need to enable any of these.
