Hi,

I sent some bitcoin using Electrum wallet. In the history tab, I got this yellow exclamation mark next to my transactions saying: Unconfirmed Parent

Here's the screenshot

I tried increasing the fees but then it says:

the server returned an error when broadcasting the transaction. Consider trying to connect to a different server, or updating Electrum

insufficient fee, your transaction is trying to replace another one in the mempool but it does not meet the rules to do so. Try to increase the fee.

This is the screenshot

I've done the following:
Connect to another server in electrum
update electrum to the newest version
use a free bitcoin accelerator to rebroadcast the transactions
The original fee is 2 sat/b, I tried increase fees a few time and managed to changed that to 6,7,and 14 sats/b respectively

But the transaction still not getting any confirmations
