How can I increase the transaction fee or what do I need to do to get the transaction through?

Many thanks for your help!
Your listed fee is 44 sat/B.

From this page, you can probably expect anywhere from 30 minutes to 12 hours at that rate.

Since your transaction was submitted more than 10 days ago, I wonder if there is some other reason it isn't getting confirmed?
