My Electrum wallet isn't connecting for some reason. I have Mac OS X El Capitan(10.11.3) and using Electrum 2.6.4. I don't want to uninstall or really mess with anything until I know what's going on. Everything was working fine a couple days ago. I just sent BTC from my coinbase account so I'm concerned it will be lost if I start uninstalling and reinstalling things while BTC is enroute. What should I do?
