Yes it's being delayed because of the fee, since you mentioned fee of 0.00001784 BTC ($1.15) which is far too low are per the current average.

as of today average fee of BTC transaction is 0.00029 BTC ~ $18.89

You have to wait for it and there is a chance it might get process when there will be free capacity in the network but it take up to days or may be weeks.

Here some online links which claim to accelerate your transaction.

1. https://bitaccelerate.com  (free, as per their claims they will rebroadcast the transaction via 10 Bitcoin nodes.)
2. https://pushtx.btc.com (not free, there might be some fee)

I'm not sure how this works in the backend but there is concept called CPFP (Child Pays for Parent)  "if a new transaction is made with a high fee, building on top of the old transaction, most of the miners will include the whole chain of transaction in the block they're mining at."
