I really can not understand why are you trying here broadcast the transaction through simple pushtx services. The issue is in bitcoin address creation, as the TC used uncompressed public key for segwit address creation (it was said here several times).
That means that broadcasting the transaction to different nodes will not work in this case. They use the same protocol and can not accept the non-standard transaction.
So what is the reason for pushing tx to bitcoin network through different nodes?
Certain nodes not running Bitcoin Core allow for non-standard transactions. Although the odds of one of these nodes mining a block is incredibly slim, it's still worth taking a shot at since the BTC sum here is considerable.
So, it's not impossible/pointless, just very unlikely.
