You are not getting new blocks or getting negative blocks?
« on: December 29, 2013, 01:17:09 PM »
Since version 0.5.3 you only have to look into your command-line-window and you'll see this:



If the "Re-scanning blockchain" is "...Done" refresh your browser (F5) and login into your account again. That's all. No need to restart the Server (NRS).
Since the last versions the web.xml has already enough good peers inside, so there should no need to add more.

As you see: Handling the Java-client goes easier and easier, week after week. ;)


Sometimes your client stops getting new blocks or it gets negative blocks, even if you have a good configured web.xml with lots of good nodes / peers.

If you're facing this problem, this may help:

1. Close you browser
2. Close your command-line-window (the Java application)
3. Go into your NXT-folder
4. Delete the files blocks.nxt and transactions.nxt
5. Remove the .bak (inluding the .) from the backup files blocks.nxt.bak and transactions.nxt.bak
6. Restart the server (start.bat)
7. Open your browser on https://127.0.0.1:7875 and login again
8. Hopefully the blocks will update after some minutes
9. This didn't work? Well, from time to time your .bak files may coruppted too. No problem. You can download the latest NXT-files here and use them.

Has anyone investigated why this happens? Reasons like NAT, client error, corrupted chain download?

This does not always work. I do not know why but sometimes after restoring the backup the block update will freeze at a certain block. Also java shows some asynchrous error on the screen.

At the moment i shut down the client and do a manual backup at times. Restoring the .bak files failed too many times for me.

Dont know what causes this, exactly when are those .baks generated?

Client is freezing after a while again and again and again … Do not know why, but it is so annoying that we all aren't able to forge some coins when the client is freezing every few hours!! All the time i have to delete the files and restart the client...

Is there somebody who can fix this ??

Kind regards!

Version 0.5.3, released today, has seemed much more stable for me.  Rest assured the devs are working on it.

If it's any consolation, forging is NOT PROFITABLE.  Just buy more coins.  They're very cheap at the moment.

Hi,

I am almost euphoric of joy seeing the developments of these new cryptocurrencies and how it all comes into place in this decentralized voluntarily way.

I picked up on crypto's from the central bankers/austrian economics perspective, like so many others has started to do from this camp, i.e., I am average clever (perhaps even a bit above) but no computer savvy engineer.

That said, while understanding the reason not pushing to mainstream prematurely (before service layers have developed a bit further), I do believe that the client and it's installation/block chain updates constantly messing up is a source for frustration for many people, including myself. Worse, potentially destroying the first impression and draining the legitimacy of Nxt.

I have installed 3 different releases, including the latest one of the client but still get stuck on incorrect blocks and the update stops when reaching "Height" 30.000 and file size 11.348KB of transactions.txt.

How come all participating and obviously sharp developers cannot fix this issue with smooth userfriendly installation and updating of block chain? It seems so much easier than everything else in Nxt?

@janbanan: Give it some time. We're in the beginning. The latest version is already much better than the versions <0.5.3. If you download the latest version 0.5.8 you will mayget negative blovks too, but there is a thing called "re-scan" and it looks like this:


When it's "done", you only have to reload the browser (F5), login again and you'll see positive blocks. If you have other issues, just download the latest NXT-files (you'll find them in the client-thread) and use them, instead of starting from scratch.

I am with you: This is too complicated. But this weekend there will be "Nxt Solaris 1.3", a windows client. In some weeks/month we'll have a major client. And like I said: What you seeing here, is the birth of a really big project. Enjoy that you can be part of it and don't be frustrated.

The latest client 0.5.10 sucks. Not getting latest blocks, and the difficulty is like 7597315 % (really). Makes it difficult to process payments for DGEX!

Updating to 0.5.11 is worth it.

Moreover, I have surprising transactions with a block icon, with void transaction ID, shown on the client frontend...
I really don't know what I could check to make it work. From the beginning, I've never forged any block (always 'incorect block' message), whereas I have more than 90knxt on it. The account is unlocked, I've made a hallmark, it is registered... and nothing : always incorrect blocks.

I've even noticed I have far more incorrect clocks with 0.5.11...

Any clue ?
