Interference with Tidal

I am having issues with the connection between Tidal and Roon Essentials, this is working perfectly for many year’s. Since 3 days I get a message after selection of the album:
Tidal: a networking or interference is interfering with tidal playback…

Tidal account is activated and i working without roon.
I restarted roon, the router, the app…, noting helps
What to do? This is really annoying
I assume its the connection between Roon and Tidal.
Please let me have asap your proposal how to solve this
