I do have a firewall running, it allows connections to port 50002, which I had set up for SSL access within the LAN.
Disabling the firewall doesn't help.
But in any case I can't even connect to 127.0.0.1:50001 on the same PC, where the firewall is irrelevant.

`sudo netstat -tunlp` returns the line:

Code:

tcp 0 0 127.0.0.1:50001 0.0.0.0:* LISTEN 45274/electrs

Looks as if your wallet is listening on a different port.
I don't know electrum though

What falvor you are on,
In case you don't know if the port is open.
have you scanned it with nmap? sudo nmap -sT -p- 10.10.8.8
