Sorry I was very busy and it was difficult for me to answer to you sooner.
The first thing is to check your current wallet release:
The last one is
v2.1.3.1 and if you installed an old version, you will find the last one here:
https://github.com/UdjinM6/Coin2.1/releasesThe second thing is to locate your Coin2 data folder:
Open your file explorer and type
%AppData% followed by
ENTER in the path field (top of the window). You should find the
Coin2.1 folder in the list. Open the folder and make a copy of your wallet.dat file on your desktop or to a USB key.
If you are not running the last wallet release, delete all the folder content,
wallet.dat file excepted, then install the last release.
If you are already running the last release, create a text file in the Coin2.1 directory and name it exactly
coin2.1.conf. Edit the Coin2.1.conf file and copy-paste these lines:
addnode=178.33.109.17
addnode=104.237.4.33
addnode=113.113.91.214
addnode=118.122.228.166
addnode=148.251.54.6
addnode=184.164.129.202
addnode=188.138.195.114
addnode=195.175.201.126
addnode=220.200.26.197
addnode=47.35.60.75
addnode=78.14.28.188
addnode=91.156.14.80
addnode=92.245.5.69
addnode=92.49.253.167
addnode=94.254.157.117
addnode=95.102.187.170
addnode=95.28.110.119
addnode=95.9.212.242
addnode=96.127.136.18
Save and close the file and try to run your wallet again. It should solve your synchronization issue, but you will to let your wallet running many hours to make a full sync.
If it doesn't work as expected, please send me a private message.
