Hi,
Please help. I'm not an expert in the technical side of things with bitcoin. I withdrew 0.0585054 BTC from a mining platform to my address, this is the transaction 11d3bfe7e0e9a5771f9a2b97b1d14f4a59b71d515aaf83222871b941aeb280b9  but it's not confirming after 24 hours. A day before that I withdrew from same platform to same address and it took a few hours.

It shows as unconfirmed on Blockchain.info what should I do?
