Transaction with highest fee, but stuck, what did I do wrong? I recently sent btc that appears to be stuck (https://live.blockcypher.com/btc/tx/c131d65d933e343f852021830b833123de952c1857f264503388cf642655c457/)

The interesting thing is that I used a higher fee (4.5 sat/byte) which was the highest fee that Electrum's slider would support. I also notice that there are only two transactions in this block. Did I screw up? Is there any way that I can fix this?

Edit: Electrum says that I am only 0.12 MB from tip, however it has hovered around there without moving and sometimes increasing in size.
The hourly average fee when this question was posted was between 9 and 10 Satoshi per Byte (sat/B).

The latest TX's that I just randomly checked all had 10.03 sat/B fee which is higher than the 4.5 sat/B that you sent.

Transactions are at a hourly peak right now. Wait it out and it'll probably go through in the next couple of hours as the mempool empties.

I just noticed your TX went through and has 3 confirmations from the time I started replying to now. So I guess this is a closed issue.
