NodeLink could not find any installed .NET Core SDKs!

I have been away from my home for some time but I started getting heartbeat error messages several days ago. I had assumed that my Raspberry Pi needed to be rebooted. I got home this evening, rebooted it and checked to see if the Nodelink server was running... it wasn't! So I tried to manually start NodeLink and got a message that it couldn't find any installed .NET Core SDKs!!

Here is the exact text from the terminal session:

sudo dotnet /home/pi/node/NodeLink.dll
  It was not possible to find any installed .NET Core SDKs
  Did you mean to run .NET Core SDK commands? Install a .NET Core SDK from:
      https://aka.ms/dotnet-download
 

Any ideas on what is causing this?

Can't say I've seen that one before.  Try re-running the install script.

That's what I did and everything seems to be working again!! Somewhat odd... 

Thanks...

I looked at my NodeLink setup on my vacation home system after seeing the issue I had on my home setup and saw that the server wasn't running there either! 

Here is what the manual running of NodeLink resulted in!

sudo dotnet /home/pi/node/NodeLink.dll
A fatal error was encountered. The library 'libhostpolicy.so' required to execute the application was not found in '/home/pi/node/'.
Failed to run as a self-contained app. If this should be a framework-dependent app, add the /home/pi/node/NodeLink.runtimeconfig.json file specifying the appropriate framework.

I re-ran the install script and everything seems to be back in order! This is an FYI...
