Electrs and Bitcoin node

I am a newbie here. I set up a raspberry Pi4 w/ 8 GB RAM and 2 TB enclosure. Started running Bitcoin Core. I was able to sync the blockchain over 2 days to a 100%. I then proceeded with downloading the Electrs app which then took about 12 hours to sync 100%. On the browser that was open the sync was complete. However if I opened another browser window the Electrs app page says “waiting for Bitcoin Node to finish syncing” with no sync at all.
The Bitcoin node is 100% synced.
I am trying to connect to a Sparrow Wallet over LAN not via TOR.
Any assistance will be appreciated.

just leave it alone for about 10-12 more hours or so.

it will give that message for a brief time when you open it in a browser or if its working.

Sparrow works great with umbrel

so you are saying after Electrs is 100% Synced you should wait another 12 hours or more for it to sync correctly? and then be able to connect to Sparrow?
Thanks
