Other things I've tried.
Make a text file called walletbuilderscoin.conf in the folder in roaming and adding all the nodes posted above.
Also tried adding them manually in the debug window but got this error: Method not found (code -32601)
Pasted in:
addnode=104.160.21.8
Also tried:
addnode 104.160.21.8 add
I don't think it is a firewall issue because 2 other qt wallets I have for different coins sync fine. Also I turned off my firewall as a test.
Anything else I can do?
Paste in the entire list i gave you exactly as i pasted it and make sure you name the config file "walletbuildercoin.conf" and make sure it's an actual config file not a text document with .conf on the end. I am guessing you are on windows 8 or 10, both are fairly restrictive when it comes to networking and can block the client from automatically searching for nodes resulting in you having to create a config file.
I have created and uploaded one for you here: https://www.dropbox.com/s/7om1frttorwiwll/Walletbuildercoin.conf?dl=1 Just drag it into the %appdata% roaming>walletbuilderscoin folder. If you are still having trouble after putting that config file in and leaving the wallet running on your computer then it is most certainly your network.
