I had a problem that wallet did not remember added nodes. I created hodlcoin.conf and copied the list https://www.coinexchange.io/network/peers/HODL
addnode=173.212.225.176
addnode=84.193.219.191
addnode=91.112.41.147
addnode=188.109.2.125
etc...
to hodlcoin.conf. The location of hodlcoin.conf is found from debug log. Like
2017-09-23 16:37:07 Using config file C:\xxxxxxxxxxxxx\hodlcoin-3.0.1\hodlcoin.conf
or C:\Users\username\AppData\Roaming\HOdlcoin\\hodlcoin.conf
Found the folder, but there's no hodlcoin.conf
You need to create hodlcoin.conf by using for example notepad. By default it's not created.
