Unable to connect to local bitcoind instance

[hex17or]

I am running a fully synced bitcoind on an Odroid box and I am trying to connect to it using the bwt-electrum-plugin on my M1 Mac. Upon configuring the options (I am using a user:password auth and not the cookie) and clicking 'Save & Connect', I get the following error as part of the Trace (note: I have blanked the xpub and the last two places of the local IP) -

Any idea why is the plugin unable to connect to bitcoind?
