Wallet from 2011 won't send to any address

the last time i was on litecoin core was in Nov 2011, I want to cash in some of my litecoins thru coinbase, but i cant send any amount to any address with litecoin core.

I Broadcasted my transaction, but the websites i used to do that fail everytime. not sure why its not sending.

Would you mind sharing a signed transaction you are trying to broadcast?

Also, have you verified that the transaction output you’re trying to spend is actually unspent?

choose wallet carefully
I have been using coinsbank since 2017, all my transactions come on time and without delay
