Trezor One does not connect

[john-light]

After connecting a Trezor One and entering the PIN (and passphrase, if needed) Frame throws an error: Please reconnect this signing device. Clicking Reload signer results in a spinning wheel and doesn't fix the problem.

To isolate the problem to Frame I have confirmed that Trezor firmware is up to date, Trezor Bridge is running, and I am able to use the Trezor with Trezor Suite desktop app and other applications (e.g. MetaMask).

Frame version: 0.6.8
OS: Linux Mint 20.3

Happened to me too.

Opened logs at ~/.config/frame/logs/main.log and found could not open Trezor Error: All backends are down error.

This led me to https://trezor.io/support/a/discovery-error-issue

And in my case it was due to my VPN connection.

I connected to a different random VPN server and it fixed the issue for me.

Thanks @matmilbury for the suggested fix. I am still having the issue. I have used other wallets with Trezor e.g. Enkrypt and MetaMask, and Trezor works with all of the other wallets I have tried. Only Frame is having this issue. So I think it's worth keeping this issue open. It would be great if someone can figure out how to make Trezor work even if some users are on a VPN (if that is actually the root cause of the problem) since other wallet developers have been able to do this. I really would like to be able to use Frame with Trezor again, and to be able to recommend Frame to other Trezor users as well.
