Description of Issue

Posting here a topic I originally opened in the software session.

I installed Roon Core on my personal laptop as of above in the Summer, successfully linking my music library that is stored in an external HDD that is USB connected to an Apple AirPort Extreme. I was not happy during my trial, so I stopped it.

Few weeks ago, I decided to give Roon a second chance due to a promotion.
Since then, I was not able to have Core recognizing the HDD.
The path is there, I tried to cancel it and re-instate it, but all the attempts were unsuccessful.
This is what Roon shows:

This is the error message that Roon shows when I try to edit the path:

This is the path as it shows from Finder:

The same path is working flawlessly via a Bluesound Node 2i and used to work with Roon in the Summer.
How can I fix this?
Thanks in advance!

Sounds like a permissions or firewall issue on the Mac? Have you followed the guide and ensured File Sharing is turned on for that folder? Delete and recreate the link in Roon after checking permissions.

Why is there no Username and Password filled in the relevant fields in the “Add network share” screen? I think these will be required.

Thanks for your replies.
Unfortunately this seems a bug I cannot get rid of

New error this afternoon:

Well, the “Unexpected Error” that you previously had was probably because you had not filled in your Username and Password.

Now, the “Unauthorized” error is clearly a permissions problem. That is probably being caused by either (a) you’ve provided an incorrect Username and/or Password, or (b) the Network Share on your Airport is no longer valid - try re-creating it and try again.
