I'm getting same error "transaction creation failed."
I last opened core in 2012.
I am able to dump privkey of my address that has btc, but when I import it to bither, it shows some other address.
Am I missing something?
If it's from 2012, no doubt your Bitcoin Core address starts with a "1"... and I'm guessing the address in "bither" starts with either a "3" or "bc1"...
- The "1"-type address is a "Legacy" address
- The "3" and "bc1"-type addresses are "SegWit" addresses.
If this is what is happening, you should use a wallet that supports importing private keys and creating legacy addresses... are you using a desktop or mobile device?

I am using mobile and bither generates address starting with 1 as well, but its different from my address.
Can you suggest another site or tool which generates legacy address from private key. Also, for my information, how many addresses can be generated from 1 private key?
