I kept getting transacted failed whenever I tried to move on an exchange or even shapeshift. I have so far tried to export my private keys and import them via Coinomi but I am starting to get errors on there.
I had 4 wallets containing ZEC, I was able to move some of my ZEC on an exchange due to coinomi. I am now getting connection errors on coinomi..
Since you have tried more than one wallet and have not worked, return your problem to connection:
Disable your firewall, Tor or VPN, these services may lead to an interrupt of your connection with the blockchain.
it is better for you to verify the transaction in any block explorer to make sure that your transaction has been completed or not.
