Viabtc can handle only a 100 request per hour and that is the limit.
By the way viabtc accepting again a new transaction id to include on their next block and I already request your txid on their tool
Hope that helps.
Edit : Your transaction got a confirmation.
Thank you very much. I think there should be more such tools as 100 is not enough for the whole community. Anyway, still, the efforts are appreciated.
p.s - locking the thread as the issue is resolved.
