Trezor one - connection to Umbrel's electrum server

Hi everyone,

I am running Trezor model one. Everything works fine while I am connected to default Trezor servers on backend. But as a enthusiast amateur bitcoiner I would like to connect to my own electrum server (I have my own node set up with Umbrel). The backend seems to be connected, but everytime I try to load hidden wallet some errors pup up (see the attached screenshot) stating that assets are not loaded correctly. Can you please advise on how to fix this? TOR is enabled on Thanks in advance.
