If it doesn't sync properly, you might have to add nodes that you can find at the explorer https://eca.ccore.online/connections (you can add them either one by one at the command line, or paste them in to the Electra.conf).

If you have more questions, there are more active people on Telegram https://t.me/Electracoin or discord https://discord.gg/FbHzrdAnGp
