Are you sure that is the txid because when I plug that into bitcoin block explorer it says transaction not found. That is odd because usual it will pop up either you got the wrong txid or the transaction hasn't gone through yet.
Hmm. I see it clearly on blockchain.info. Check it here:

This might have been a good enough fees, but right now the network is so congested that this will never go through. Right now I think the minimum amount of fees are about already 700 sats/byte to get a transaction to go through within the day. I guess your only hope now is to have it accelerated or if you have enabled increase fee option then you should do so. This will take forever to confirm without doing anything.
