Tidal connection issues

Hi.
I’ve been happily using Tidal with Audirvana/Audirvana remote for 18 months or so with no real problems. Over the last week I’ve started to experience the following issues:

Audirvana will not automatically connect to Tidal, instead I’m redirected to the Tidal website to sign in. This happens every time Audirvana is reopened. After signing in, Tidal appears in the “connected panel” but still shows unconnected in system options. However, it does play locally on my IMAC (running Catalina).

I also use the remote, in conjunction with Mo0de running on an RPI, on another system. Tidal now does not show up at all in this case. As stated above it has been working perfectly until this week.

Any help with these issues would be greatly appreciated.
