I have the same question as OP, if anybody can help me it would be awesome, viabtc is not working now:

You do not have any problem. You do not have unconfirmed input or low tx fees. 150 sat/Byte is already large enough. Your tx will confirm in a few hours, just wait it out.
That's more than 24h I'm waiting, I know that 150 sat/byte should be enough, but seems that the mempool is being spammed again.
I hate slow and expensive tx...Will segwit /segwit2x save us from this happening again?
