Confirmation Mismatch

[Elliander]

I sent Bitcoin from one of my Coinbase wallet to Electrum. In Coinbase it shows as completed. It Electrum it shows as a -1 Confirmation. In Blockchain.info it says there are 29 confirmations for the transaction.

Similarly, around the same time, I sent Bitcoin from Bitminter earnings to the same Electrum address. It also shows as having a -1 confirmation, but Blockchain also shows it as having 29 confirmations.

Since I am in control of all points I can see that the Bitcoin has indeed left the originating addresses, but I am not really sure what to make of this problem. Exiting Electrum and opening it again refreshed to show that each does indeed have 29 confirmations, but what causes this type of mismatch problem? What should I do in the future if it happens with Bitcoin that someone else sends me? And if this is a bug in Electrum 1.9.8 why isn't there a refresh button for cases of people using it in a bootable mode?

You need to wait Electrum to complete it's syncing.

Electrum's blockchain should be back at time. When it's synced you'll see confirmation.

Rarely I'm experiencing the same problem too but sometimes Electrum also justs never finishs the sync.
Electrum is a great program but it has also this annoying quirk, the only solution I know is to restart Electrum and hoping its getting better.
If you're just receiving bitcoins it's sufficient to look up the balance at coinbase and blockchain.info

How long is the synching supposed to take? Because it was a few hours and was only corrected by exiting the software and reopening. If there is a problem with it not properly synching at times there should be a way to tell it to synch manually.

Restart electrum and it will show the correct amount of confirmations.
