So using whitelist=127.0.0.1 would allow localhost not to be counted amongst the connections subjected to maxconnections, correct? Thanks!
IIRC, using it while having maxconnections set up, will reserve any local service(Electrs) that I used to keep still connected.
I looked at my config and I already had whitelist=bloomfilter@127.0.0.1 ...
What kind of local services you are trying to connect to? Do you have any logs when it rejects the connection attempt?
And have you tried to include all the [permissions@] in the config?
