Fulcrum slow on umbrel OS 1.2.2 on Raspi5

I gave up on Electrum install as it appears to be a buggy version included in the app store.
I am trying Fulcrum but I see errors also:

umbrel@umbrel:~$ sudo docker logs 26ea3beb7572 | tail -50

}
and then, later in the log:
Electrum attempting reconnect…
Electrum attempting reconnect…
Electrum attempting reconnect…
Electrum attempting reconnect…

Electrum attempting reconnect…

forever.

Anybody know what’s causing this?

Also, at start of log for the “fulcrum_fulcrum_1” container:

Can someone help me fix this? At this rate it will take about a week to finish indexing.
Is there some configuration I can tweak for this to speed it up?
I have 8G RAM and it’s only using less than half of it.
