Generated a transaction id but not seen on blockchain
High S value error indicates that a signature in your transaction doesn't adhere to BIP-62, i.e. that your signature is non-default. This is the same issue that has been levered in many of the past transaction malleability problems. This could happen for example if you use a very old version of your wallet software.

If your transaction hasn't propagated in the network, you should be able to create a new transaction with the same inputs. It might have been malleated and broadcasted with a different signature though, which would give it a different transaction id. If that's the case you should be able to find it by looking at the addresses of your inputs.
