You have to tell the sender to pump the fee.

If he is not answering you, you can use child-pay-for-parent to pump the fee on wallets like Electrum or Bluewallet. If you use child-pay-for-parent to pump the fee, use 26 sat/vbyte.

By using child-pay-for-parent, you will send part or all the unconfirmed transaction to another address on your wallet. Before a miner can include your transaction (child transaction ) into a block, the miner has to include the parent transaction (this unconfirmed transaction) into a block as well, but the fee you paid for your transaction which is enough to get two transactions confirmed will make a miner to include both transaction into the same block early.

I couldn't submit it to ViaBTC accelerator due to the transaction size, but I can see that you're using RBF so you should be able to increase the fees. Which wallet are you using?

Also, which service are you sending the funds to? Some services may not process your transaction once you bump its fees.

Your tx have status RBF and you can change fee for fast confirm
