Hello,

I have my wallet in Bitcoin Core old 3 years, and I have some money on my wallet.
I want to make withdrawal, and I can't because... I have my private key also I export wallet.dat.
Problem is if import key to electrum or bitcoin.com I got different public address and in different I dont have money...

I have make one test in another pc and I only replace wallet.dat I got the correct public address.

How is that possible?
