Problem solved. I replaced the current wallet.dat file  by one week old wallet backup.
Now there is no existance of my first transaction in the list, I got my unsent balance again.

But not sure why this transaction was not broadcasted. So don't forget to keep your wallet
backup regularly.

Thanks

I am continuously connected to net. Even if it is disconnected occasionally all transactions
are executed as soon as it is connected to net again. Using btc more than a year, but never
faced such a problem before.

Hello

I sent 0.05411btc to 16cC2ASPs4MAMNTTfLKh7esmxXGneKHC6F from my bitcoin core wallet yesterday.
Transaction ID (ee571cb95553992dc28ac5bd18a566e91899727337c95949cd225fdc93b2680f-000)
Almost 16hrs past there is no trace of the transaction in blockchain.info. My wallet ballance is reduced
but receiver did not receive the btc.

Today I sent again 0.003btc to the same address. This time it is showed in blockchain.info
instantatnuously. Any body can help me out? May be connected to 'spend unconfired change'
in core wallet option.

By the way, I am running bitcoin core and it is up to date and synced as of now.

Regards

Thanks a lot for your suggestions.

Interestingly, though I was using IP, in ghash account stats was showing
everything perfectly.

 

I started mining few weeks ago. After several experiment, I started mining with ghash.io.
Everything was fine until yesterday except downtime of their site. I was earning steadily
from this pool.

To improve connectivity I used their ip(stratum+tcp://88.150.205.242:3333)
instead of stratum+tcp://uk1.ghash.io:3333. I found no problem with it. Everything was
ok in my account with ghash.io. It was showing shiftworks, shares, hash rate, changes
in hash rate etc. perfectly.

However yesterday ghash.io was getting fewer blocks than usual. I checked
blockchain.info and found that blocks found with ip(88.150.205.242) were not distributed
among the miners. Only blocks found with ghash.io were shared with miners.

Very interestingly after my complaint ghash.io is again getting block in their usual manner.

My concerns
1. Is it really matters in using ip:port or domain:port
2. If ip:port is not acceptable, why the site showing all my info
3. Are they stealing BTC from miner secretly?

Waiting for their reply.
