Thanks for the help.  I completely deleted the blockchain and wiped everything crypto from my computer (restarted it)  and then reloaded a new installer from Jelurida.  The client starts up and says its downloading the blockchain but hours pass and there aren't any blocks downloaded.  I've restarted the computer and done every trick I could thing of to no avail. 

Any additional advice?

Release 2.2.4

sha256 checksums:



The exe and dmg packages must have a digital signature by "Jelurida Swiss SA".

Change log:

This release introduces the StandbyShuffler add-on, a new feature intended to
simplify the use of our flagship privacy feature, fully decentralized and
trustless Shuffling.

A StandbyShuffler, as opposed to a regular Shuffler, does not start a new
shuffling immediately, but runs in the background and waits for other users to
start a shuffling which matches the StandbyShuffler parameters - holding (coin,
asset or currency), minimum and maximum amounts, and number of participants.
When such a shuffling is created, the StandbyShuffler joins it automatically. A
StandbyShuffler is configured on start with a number of recipient public keys
to use as recipients in each shuffling it joins, and shuts down once all have
been used.

Running a StandbyShuffler requires a full node, not just a light client.
To enable the StandbyShuffler add-on, add nxt.addons.StandbyShuffling to the
list of enabled add-ons in the nxt.addOns property. This add-on registers three
new APIs:

StartStandbyShuffler - start a StandbyShuffler. The secretPhrase of the
shuffling account must be supplied. The holdingType and holding parameters
define the coin, asset or currency for which to listen for shufflings being
started. The optional minAmount, maxAmount and minParticipants parameters can
be used to limit which shufflings to join. The recipientPublicKeys parameter
holds one or more public keys, used one at a time as a recipient account public
key each time a shuffling is joined. This can be specified either as a multi-
value parameter, or a single text value holding multiple public keys separated
by newlines. The feeRateNQTPerFXT parameter specifies what rate to use when
calculating the child chain fees for each shuffling transaction submitted.
Since the market rate can change between when the StandbyShuffler is started
and an actual shuffling is joined, one should use a high enough rate to make
sure shuffling transactions of the StandbyShuffler account are always bundled.

GetStandbyShufflers - returns a list of all StandbyShufflers running on the
node, optionally filtered using holdingType, holding and account parameters.
If not running locally, a secretPhrase or admin password are required.

StopStandbyShuffler - stops the StandbyShuffler for a specified account and
holding or all StandbyShufflers running on the node if account is not
specified. If not running locally, a secretPhrase or admin password are

An UI for starting, observing, or stopping StandbyShufflers has been added
under Shuffling / My StandbyShufflers.

To automate starting the configured StandbyShufflers when the node is
restarted, a set of StartStandbyShuffling, SaveStandbyShufflingEncrypted, and
StartStandbyShufflingEncrypted add-ons has been provided.

StartStandbyShuffling automatically starts one or more StandbyShufflers as
defined in a file set in the nxt.startStandbyShufflingFile property. The
format of this JSON file is the same as the JSON output of GetStandbyShufflers,
with secretPhrase field added for each StandbyShuffler, thus the simplest way
to generate it is first to setup StandbyShufflers as required and then save
and edit the GetStandbyShufflers response.

Alternatively, to avoid keeping the secretPhrase and recipient public keys in
a plain text file, the SaveStandbyShufflingEncrypted add-on can be used to save
the StandbyShufflers configuration JSON in an encrypted file, and the
StartStandbyShufflingEncrypted add-on to start them by submitting the
decryption password through the API.

Added ChangeNOW as an integrated exchange in the wallet, allowing exchange of
Ignis and Ardor to any coin supported by ChangeNOW.

Permanently disallowed outgoing transactions from the new @ArdorBurnAccount,
see announcement at

Pause forging if there are not enough connected peers from which to download
the blockchain, as defined in nxt.numberOfForkConfirmations or
nxt.testnetNumberOfForkConfirmations, unless nxt.isOffline=true. This is to
avoid building a fork if the node is temporarily disconnected. To disable this
behavior, set nxt.pauseForgingOnNoConnection=false (default is true).

Do not allow accounts under account control to start a Funding Monitor.

The SaveBundlingEncrypted, SaveForgingEncrypted, SaveFundingMonitorEncrypted
APIs now require admin password when running on a remote node.

Added a list of full transaction hashes with chain ids to the response of the
getUnconfirmedTransactionIds API.

Added a new bundling filter, nxt.addons.TransactionTypeBundler, which bundles
only transactions of the transaction types specified in the filter parameter.
The parameter must be a comma separated list of <type>:<subtype> pairs with
the "type" and "subtype" of the whitelisted transaction types.

Improved propagation of bundler rates between peers and calculation of best
bundler rates. The CalculateFee, GetBundlerRates, and all CreateTransaction
APIs now take both minBundlerBalanceFXT and minBundlerFeeLimitFQT parameters,
with defaults based on the nxt.minBundlerBalanceFXT (default 1000 ARDR) and
nxt.minBundlerFeeLimitFXT (default 10 ARDR) properties.
Bundlers with effective balance lower than minBundlerBalanceFXT, or remaining
fee limit or available ARDR balance lower than minBundlerFeeLimitFQT, are
excluded from the best rates calculation.

Shamir secret sharing passphrases can now be used to sign transaction

Updated Jetty to version 9.4.18. This release fixes a Jetty bug which causes
a server hang after high load, therefore an update is highly recommended.

The Jelurida Public License has been updated to version 1.2, to clarify that
Ardor code is not portable to Nxt clones unless the JPL requirements for Ardor
are also satisfied (article 3.4.2 of the General Conditions), and to require
that airdrops, including the fact that they are done in order to satisfy the
JPL, are announced at least a month before the planned snapshot date (article
2.2 of the Special Conditions).

Thanks,  localhost:27876 worked to bring up the wallet interface in my browser.

I did end up finding the issue, which is with the most recent OpenJFX packages that apt-get supplies. OpenJDK-11 no longer supports OpenJFX for whatever reason, so I had to downgrade my OpenJFX packages in order to get them running with OpenJDK-8.

I followed those steps and made sure Ubuntu was using Java 8 by default, ran with no errors, and everything worked fine from there.

...For the linux installation package, the code is compiled with OpenJDK 8, and
can still be run under either Java 8, or Java 11 or 12...

It's strange what's happening to you, and it looks like a java conflict to me

If the service is really running in the background, even if the GUI doesn't launch automatically, you still should be able to accesss to the wallet interface by typing in your web browser localhost:27876

Moreover, for Linux (or any other OS) you can try with the Platform Independent Zip Package (which doesn't require installation, you just need to unzip it - available from the Jelurida website) and launch the wallet service by running in the terminal. And then localhost:27876 in your webbrowser to access to the wallet interface

Won't run from the shortcut or "" either. I get essentially the same result, except without the feedback from the terminal. If I run "" in the terminal it will give me the error that JavaFX is not supported and show the server running in the terminal despite never launching the GUI. If I run from the shortcut, I don't see anything at all, the nxt_db folder will grow in size as if the server is running and downloading the blockchain, but the GUI never launches. Do you know what version of Java it's compiled with by default? If I don't compile first, I just get an error message and the executable was compiled with an older version of Java and I have to compile it to start the server.

When I've run it on Linux in the past, I've always compiled past versions of Ardor by running "" and I'm able to run from "" or "". Definitely seems like there's some conflict preventing Ardor from recognizing and using the OpenJFX libraries.

Thanks for your response, I'll keep searching.

If you are using the Linux installer, I don't think you need to compile anything.

1- First Install the wallet: sh

2- After the installation is completed, two icons will have been added to your Ubuntu program menu:
Ardor Start (which links to
Ardor Stop (which links to

To run the wallet, just click on the Ardor Start icon. An Ardor icon will appear in the notification area and the desktop wallet should pop up a few seconds later. To stop the wallet, righ click on the Ardor icon in the notification area and then click on Shutdown.

To delete and redownload the blockchain file:

1- stop the service (righ click on the Ardor icon in the notification area > shutdown

2- Locate the nxt_db folder and delete its content (In a Mac it should be at ~/.ardor) >

3- At this point, either you start the blockchain download from scratch by just running the client (and probably having to wait some hours) or you follow the instruction shown here to download a copy of the blockchain file to speed up the process before running the client
