I submitted it to the viabtc website, and it says its accepted it. If you are prepared to wait the viabtc mining pool will confirm it for you. It usually mines a few blocks a day, so you might have to wait 12 hours for it to find another block. This link shows the times it mined its most recent blocks.
https://blockchain.info/blocks/ViaBTCThe bitcoinfees website says the fee your transaction pays should get it confirmed in between an hour and 8.5 hour's time.
Your transaction is OPT-IN RBF, so you could right click it in electrum and create a new transaction with a higher fee to speed up its confirmation time. However, only some servers that electrum connects to will accept such new transactions.
If it doesn't work at first then click the green circle at the bottom right of electrum, and a new window should open. Inside it uncheck "select server automatically", then select a new server from the list and click the OK button. Try broadcasting the RBF transaction again, and repeating the process until you find a server that will accept your RBF transaction.
