Lighthouse is now 're-available' at : http://www.vinumeris.com/lighthouse
The site has had its layout refreshed so I imagine that is why it was unavailable this week.

Lighthouse use of wallet words is compatible with MultiBit HD so try using that to restore your wallet.
There are downloads for Windows/ Mac/ Linux

@chemodan @alexfront

The github user GreenOut sent me his wallet + password yesterday.
After a repair wallet (on my machine) everything was ok.
See: https://github.com/bitcoin-solutions/multibit-hd/issues/862


Thus it would be very useful if I could have access to your wallets to see if I can reproduce the problem (and hence investigate it).

Would you be willing to 'burn' (i.e. never use again) the wallet where you had a problem ?
Then I can have a close look at it.

This would entail:
1) Empty your wallet of all bitcoin and never use any of those addresses again.
2) Send me, zipped, the original wallet directory - this will be called something like 'mbhd-1111111111-222222222-333333333-4444444444-555555555555'.  Email it to me at [email protected]
3) Send me your wallet password and wallet words.

Obviously I would be able to see your transactions and notes so I would understand if you didn't want to. Also, if you mail me it you can assume that someone, somewhere will be snooping on your data.

@chemodan Good that you have access to your bitcoins.

Well yes it is a bug but it is affecting 0.006% of users (i.e 99.994% of people don't experience it). Those users affected have their wallet words so can reconstruct their private keys to access their bitcoins.

The Bitcoin network is complex. Bitcoin wallets are complex and are developed with tiny, virtually non-existent, budgets.
Your feedback is actually part of the process of improving the software for everyone else though I appreciate it's inconvenient if you are the one encountering problems.

Well, the problem is solved. I just installed the version 0.1.4 and refused to update at startup. I repaired my wallet with the words and now all coins on my balance. These are no transactions with unknown status. There is no doubt the version 0.2.0 have critical bug

jim618, you should take measures emergency

So this is some other bug then. So you don't have any other suggestions to fix? I might not be able to use an iphone. I'm not sure.

On the github issues database, user GreenOut tried the same technique and it worked successfully:
https://github.com/bitcoin-solutions/multibit-hd/issues/862#issuecomment-185816284

I would try and get access to an iPhone yes and use BreadWallet yes.

The sync just finished and it did not work. My whole wallet is still showing as unconfirmed. Any other suggestions? I don't have a iphone. I may be able to use one this weekend though but I would prefer not to.

I think there is actually an attack on the Bitcoin network at the moment where someone is firing up lots of Amazon virtual machines that grab bitcoind connections. Ironically they are using both MultiBit Classic and HD to make these connections. That will leave less connections for real users.

If you find that your sync slows down to nothing then you can try restarting your MultiBit HD and it will make fresh Bitcoin network connections. That can help sometimes.

I'm trying the "fresh wallet" as you stated and I can't even get it to finish syncing. It stalls around 50%.

@alexfront About 90% of our downloads are on Windows and the code base is virtually identical so I don't think it is that.

@chemodan Please be patient. Constantly posting doesn't actually progress anything.

Most likely it is a bug as it has also been raised here:
https://github.com/bitcoin-solutions/multibit-hd/issues/862

It is most likely a combination of two separate bugs, probably:
1) Transactions losing their transaction confidence. There is an object Context which looks after these and it's been a bit problematic in the past.
2) Wallet synchronisation is probably not handling the transition Unknown -> Confirmed correctly.

The incidence rate of this bug (3 instances in about 50K usages of v0.2.0 so far) would indicate that it is a combination of circumstances.
These bugs aren't terribly easily to reproduce. Both these areas of responsibility are in the Bitcoin network management code, bitcoinj, rather than the MultiBit HD code itself.


Anyhow, there are a couple of possible workarounds:
1) You should be able to use your wallet words in BreadWallet. This is an iOS wallet only.
2) A fresh wallet recreate may avoid the 'Unknown status' problem so can someone try this:

A) Open MultiBit HD, enter your wallet password and then goto 'Manage wallet | Wallet dashboard' and write down:
    i) The application data directory
   ii) The wallet directory. This is in the format 'mbhd-11111111-22222222-33333333-44444444-55555555'
B) Close MultiBit HD
C) REALLY make sure you close MultiBit HD. It's important
D) Go into your OS's file exporer and rename the wallet directory to 'old-mbhd-'
    What this does is makes MultiBit HD 'forget' about the wallet and transaction status
E) Open MultiBit HD and do a 'restore wallet from wallet words'. Follow the wizard and enter the wallet words for your wallet.

This should do a restore from nothing and do a clean sync with the Bitcoin network.
You'll lose your notes and exchange rates but I am hoping that all your transactions will confirm (assuming they actually ARE confirmed on the Bitcoin network).

Once someone tries this can they report back if it works as it will be a useful workaround for others.

Good to know. Well all I know is it's definitely a software issue.

Dear jim618, now you are aware. Wnen you and other developers fix this biggest bug? The bug appears only in 0.2.0. Also why previous versions (0.1.2 or 0.1.4) cannot connect if I install them?

Not only Windows. On Ubuntu same result

Is there some bug in the windows version of the update (0.2.0)? ...because both chemodan and I are using windows.

The repair just finished and it's still unconfirmed.

I have already tried a repair twice. Still no luck. I'll try it again here but I'm pretty sure this is just a problem with the new update not recognizing my transaction as received.

@chemodan
As this transaction is now confirmed (98 blocks deep when I looked), have you tried a 'Tools | Repair wallet' to resync your wallet to the blockchain ?

According to your posts, you have tried doing a restore of your wallet.
Restore is primarily for when you need to recover a backup (say you've lost your laptop).

There is help on pretty much all aspects of using MultiBit HD available in app.
If you have a read of:
https://multibit.org/en/help/hd0.2/repair-wallet.html

You'll see that doing a 'Tools | Repair wallet' will resync your wallet to what's on the blockchain.
Try that.

I have same trouble. I lost much money with it

chemodan, It does have Unknown status in Multibit so something in the program is reading it incorrectly.
