Script Crashes after 7 hours of mining.

Hello. I’m using this script to mine a sha256 genesis block but after 7 hours of mining it crashes with this error. Note: The script actually works if i start it without any parameters(by doing so i presume i mine satoshi’s genesis block and it works )

bits: 0x1d00ffff
Searching for genesis hash..

There needs to be code written to also iterate within the coinbase, the famous newspaper headline. 4294967295 is bigger than 0xFFFF FFFF

Same issue. Tried a shorter timestamp and still got the error. Original BTC timestamp is 69, mine was 65 so I think that is not the solution
