this is really strange, its got over 112 confirmations..
Even if there is no confirmation on the blockchain, the transaction would be visible in your Electrum wallet (assuming the wallet is synchronized). If you do an Electrum check for that particular address this way : View -> Console -> then type:
ismine("YOUR_ADDRESS_HERE")
you should get result
true.
If both addresses match (Electrum + blockchain), then the problem is definitely in the server to which Electrum connects so follow the link Maus0728 posted. If none of the above helps, it may be a corrupt file that is causing problems, so in that case one of the solutions is to delete the
blockchain headers file in the main Electrum directory, and then open the wallet and try to sync again.
For location of file check ->
Where is the Electrum datadir located?Before any deletions or any radical actions, check the seed (12 words) and save them safely as this is the only way to wallet recovery.
