Hello

I've been struggling with an issue all day and need some assistance.

I transferred funds from Coinbase to my account, but noticed Coinbase uses several unconfirmed hashes (Parent) for the transaction. Receiving this through Electrum, I attempted a CPFP (Child Pays for Parent) but the transaction fee was too low for its large size, about 85 KvB.

When trying to increase the fee in the new hash (setting it to 20,000 sats for 110 vBytes), I encountered an error upon signing and broadcasting: 'The server returned an error when broadcasting the transaction. Consider trying another server or update Electrum. Fees exceed maximum configured by user.'

I was able to set 10,000 sat

Even attempting to sign the transaction and broadcast it manually on different servers resulted in the same error: 'Code: -25 Error: Fees exceed maximum configured by user' (referring to settings like -Maxtxfee, Maxfeerate).

Can anyone provide a solution to this? Your help would be greatly appreciated.

Regards,
