MultiBit HD

[Mirdude]

Same error for past 24 hrs: https://gyazo.com/a477dc33767931ba09e46457629e8d67

Tried uninstalling, updating to the newest version etc, I think it might be a network problem with ports, but I'm not sure how to fix that, any suggestions?

Yes, it looks like it cannot sync.
MultiBit HD need ports 8333 open so that it can connect to the Bitcoin network.

If you have that port blocked or a firewall is blocking it then you won't be able to connect.

Also, rarely, if you have a bitcoind running locally and have some fancy port forwarding rules that can do the same.

Networking/ firewalls depends very much on your operating system and your local network setup.

Well, it's been working fine for ages, only recently encountered this problem, have used it for 2+ months and there's been no errors at all.

I tried to open the port using Windows Firewall and creating new rules, but don't know what I've done wrong:

Hoping someone has a solution for this problem, I have like .6 BTC stuck in there :S

Does it work if you temporarily disable the (windows) firewall? Do you have any other software that might cause this?

Turned it off and still the same issue :/
I don't think I have any other Anti Virus system etc that would stop it, this only occurred recently and I've not made any downloads/changes at all.
Was working fine for 2 months, but idk what's going on now :S

You could try downloading Lighthouse (https://www.vinumeris.com/lighthouse) and use your wallet words in that.

Lighthouse is also based on bitcoinj (same as MultiBit HD) so if it is a port thing then that would probably exhibit the same lack of connectivity though.

Already downloaded Lighthouse to solve the issue, and I don't know my wallet words :S

How about trying a different network ?
Coffee shop wifi is normally fast enough to sync.

Also, if you don't have your wallet words you really should empty that wallet and create a new one.
WRITE DOWN THE WALLET WORDS of the new wallet.

Without your wallet words you significantly increase your chances of having problems as you cannot restore your backups or create your wallet afresh on a new machine.

I tried my grandma's WiFi, and still the same issue.
Might be a firewall/port issue, getting new Internet anyway tomorrow.

If I empty it, where does the BTC go, because I have like $200 worth nearly.

[jim618]

When you empty your wallet it asks you for a bitcoin address so you can send it wherever you want.

No option to empty it at all, any other ideas?

It's in Manage wallet | Empty wallet

I see that, but it won't let me click it: https://gyazo.com/ee1c8043841911215b736e83c21953cc

Will pay someone $10 if they can help me sort this via Skype.

Try this:

I see "There was an error in creating a connection to the Bitcoin network" in the corner

You most likely have a corrupted file in your wallet directory. Here's the procedure to resolve the situation:

1. Start MultiBit HD as normal
2. Unlock your wallet and click Finish as normal
3. Click "Manage Wallet" in the sidebar and click the "Wallet dashboard" button
4. Make a note of your "application directory" and your "wallet directory" (copy/paste into a text editor is useful here)
5. Close MultiBit HD in the usual way
6. Open a file browser and navigate to the "application directory" and from there into your "wallet directory"
7. Locate the file called mbhd.spvchain and delete it
8. Start MultiBit HD as normal and unlock your wallet
9. You should now be able to connect to the Bitcoin network and after a much longer synchronization process than usual your balance will be restored
