I've been mining solo all day!
Rather than executing "eurobitd --add-peer blah blah I created a file called eurobit.conf and saved it into my appdata\roaming\eurobit folder (I'm on Windows 10).
All that's in it is the following.
add-peer=35.226.137.84:8080
add-peer=35.188.44.219:8080
I can then execute eurobitd.exe without any command line parameters.
It might take a while to sync so be patient.
Did you actually see some action in the cmd window whilst synching ?
nvm, still getting connection refused errors (set_log 4)
