Umbrel Bitcoin Core Node not connecting to Specter Desktop over Tor

Hi,

I'm currently running a Bitcoin Core Node on UmbrelOS with Umbrel Home and am attempting to connect my Specter Desktop application to my Node. My Bitcoin Node runs over Tor, and Umbrel's application makes it incredibly easy to copy the appropriate password and host onion address for the connection. The problem is that the credentials are never accepted in the Specter Desktop application, where I have continuously received the following error:

For reference, my /umbrel/app-data/bitcoin/data/bitcoin/bitcoin.conf in the UmbrelOS Terminal looks like this:

Load additional configuration file, relative to the data directory.
includeconf=umbrel-bitcoin.conf
server=1
rpcuser=umbrel
rpcpassword: copied directly from the node

I'm relatively new to this, so I apologize if this is a stupid question. I would greatly appreciate any advice on getting this connection working.

Start with the Bitcoin Core connection settings in Specter Desktop and compare them with the Umbrel bitcoin.conf values shown in the report, including the onion host and RPC credentials. Reproduce the connection attempt over Tor and determine whether the reported credentials are accepted; done means the Umbrel Bitcoin Core node connects successfully from Specter Desktop.
