I think that you are being limited somehow by that electrum API, it only let you 6 tries?
I think that it should give you a more detailed error of why it fail.

I don't use electrum at this time ~~

my BOT is writed by python and bitcoinlib

about 6~7 second POST RatTX to https://mempool.space/api/tx

I think I gave away too often and didn’t calculate BTC/kvB properly.
