Why is there a Server error? (Why is it taking so long for my BTC to send/receive?)

There could be a number of reasons:

1) The bitcoin blockchain could be congested;

2) You may not have sent enough BTC to expedite the transaction (you can pay a higher mining fee to relay your transaction faster);

3) Or there could be an issue with one of our third-party relay systems that we use to display balances and push transactions.

Please try to give it some more time (it could take up to a few hours if the blockchain is congested) before contacting support.
