There are many causes for failure, can you write down the failed message that appears?
Make sure that the ETH address of your exchange wallet is correct and that you have enough GAS to send ETH.
"sorry, we can't find the transaction hash"
That is one error.
The other option is something like "transaction started 2 days ago", stimated end "4 hours"... and it always is 4 hours, even 4 hours later

I tried the same with 200000 , gwei 40, which was 5 usd in fees and didn't work.
