specifically, i had the wallet in sparrow, i exported the xpub or maybe zpub as a qr on my lap top, i scanned the qr with green wallet running on my electrs, with tor on in app, and it worked 🤷♂️

Thats what i just did exactly the same way as you from sparrow.
Both Green and Blue failed to connect 😟
Sparrow connects to the same node without issues.

hmm, darn. have you tried using orbot vpn instead of native app tor? sometimes i have better luck with that
