Hi @Klaus-19,
I’m very sorry for the prolonged delay in responding to and resolving your issue here. The Tidal login issue you’re describing suggests there may be a Firewall at play.
Since you are using a Windows PC, I would verify that both Roon.exe and RAATServer.exe have been added as exceptions to your Windows firewall.
You can use these instructions to add the exceptions and the executables themselves would be located in your Database Location/Application folder path.
I would also add these exceptions to any Antivirus or other Firewall blocking applications you may have and ensure that you connected to your network via a Private network, not a Public one, see this guide for more information.
Please let me know if you continue to experience issues and we’ll promptly circle back. I’ve set this thread to alert the support team when you respond.
