When I want to make a transaction I follow these steps
- Create order in the ONLINE computer
- Copy transaction to a USB
- Plug USB to OFFLINE computer
- Load transaction from file
- Plug TREZOR
- Sign transaction
But during the signing process an error popups with a message similar to "Unable to connect to servers ". In my opinion it makes no sense, it is supposed to be an offline wallet. There is no need of a server to sign the transaction. ¿Am I wrong?
As far as i know, both computers use the same Electrum version (2.8.3)
