I don't think the solution is as simple as changing the electrs configuration to use 10.152.152.10:9111 instead of 127.0.0.1:8333 because electrs isn't supposed to connect to the internet.
"
romanz/electrs" right?
Otherwise, Blockstream's fork is designed towards being a public Electrum server.
Try setting that option if it can actually connect to Bitcoin Core (
p2p).
If it did, try "
127.0.0.1:50001" in your "
electrum_rpc_addr" config since electrs will only listen for Electrum clients on that address not the one in "
daemon_p2p_addr".
