Trezor Suite error - Backends are down

Using Trezor Suite 21.2.1 on Windows 10 64bit. When I launch the Suite and connect my wallet, an error message appears “all backends are down”.

Wallet works with Trezor for Web. Tried disabling/enabling TOR, per support post, no difference.

It should work if you turn off TOR and restart Trezor Suite, but it may also be a temporary error so please wait and try again later.
