Can you access Trezor Wallet?
We need to know whether the issue is with the connection in general or if the issue is related to the given wallet only. If you can’t access Trezor Wallet, please see the Wallet issues subcategory.
If you can access your account with the 3rd party wallet, then the Trezor integration seems to be working and the issue is most likely with the given wallet’s interface. Please contact their support directly with your inquiry.
