The absolute fee on your transaction doesn't matter. What matters is the fee rate. The fee rate of your transaction is 107.8 sat/vByte which is okay. However your transaction depends on a transaction that pays a fee rate of 17.7 sat/vByte. This is very low for the current network conditions. Your transaction cannot confirm until this low fee transaction also confirms.

This explains it better. Thanks! Should I increase the fee in my next transactions to avoid these kind of delays? Or how do I determine the fee rate before sending?
