Troubleshooting and FAQ

New Version of our UlangoTV App is 1.5

The most recent Version of UlangoTV will allways be loaded first when synchronizing with our Server (IP But this will only work with SmartHub based Samsung TVs up to Series H. Owners of the newer Tizen-based TVs (Series J upwards) have to download a zip file and install via USB. A detailed description is available here: You find the download link in the UserAppStore on the SyncApps Page below the logo of our UlangoTV app.

Frequently asked questions on IPTV wit UlangoTV

Some streams stop, break or freeze completely

We do not have any handle on the performance of the servers behind our URLs. Most certainly problems are not between your TV and the internet provider. Somtimes servers are overloaded or reject access because of multi-user restrictions. We are constantly measuring quality of the streams and try to present the best up front. But sometimes there is just no better choice.

But there are also client side problems and dependencies on the Model Series of your Smart TV. Known Problems are:

Series D and below do not play some streams because of frame rate problems

Series E and below are more sensitive on missing stream segments due to server side capacity problems

Series J does not play the autdated flash streams (rtmp://) any more

Some Streams will not start

Our collection of streams is very dynamic. A lot of stream URLs are published and withdrawn shortly after. It's a steady come and go. Our Scouts are working hard to fill the gaps.

What do the Usability numbers mean in the UlangoTV App

These are measurements based on real access of UlangoTV to the streams server. Numbers are gathered anonymously on the end of every tv session. Usability is the ratio between the time of a working live stream and the total time. Only streams with values > 80 in all time ranges will offer an undisturbed TV experience.

Just recently we started to measure the usability values separately for each smart TV model series and are displaying these values in our Ulango TV App

In the future we will present playlists that are optimizes for the specific model series - just as we did for the apps in our UserAppStore

The UserAppStore lists apps from many nations with may languages. Among them are apps, that are not listed in the Samsung Appstore.  There are also apps that are not running in some countries or that are requiring a specific TV-Model - e.g. H Series.

Questions we hear very often...

What is my TV Modelseries?

Example: Model UE55F8090 belongs to the F-Series.
Following the size in inch, there is a single letter with the series name.

What do I have to configure on my TV?

We are providing a little video for each of the Samsung Series

J-Series (Tizen OS): You need the App as a ZIP File to be installed with an USB stick. You find the download link in the UserAppStore on the SyncApps Page below the logo of our UlangoTV app.

I can't login as "developer"!

Signing in as developer should always work. Some models, such as the C-Series (PW:0000) or the D-Series (PW:000000) require a trivial password. With newer models the password field must be left blank
Attention: Do no generate a new account “develop” - just sign in.

Which IP-Address do I have to enter on my SmartHub device?

The current IP-Address of our UserAppStore can be found under the Submenu Smart-TV-Apps -> SyncApps

I do not see any Apps in UserAppStore!

Most probably you have some filters active - clear them using the link at the top of the filters region

I selected some Apps - but only one App with a Samsung Logo gets installed.

This happens when the IP-Address we have stored, when you did the app selection on your PC does not match the IP-Address of your TV. Your current external IP-address (the address, that is saved to our database) is listed on your "My Account" page. This must match the IP-Address that is shown on the TV, when you are opening the App with the Samsung Logo.

I selected some Apps - but none or only some of them gets installed!

On the Page Smart-TV-Apps -> "SyncApps" there is a check box at the very bottom "Use the global SyncApps list available for everybody". The principal correct synchronization can be proved by syncing after this has been selected. A single App will be installed with a Samsung Logo.

The most probable reason for the freeze while syncing is an incompatibility of one of the selected apps with your TV Model. Find the problematic App by succesively cutting the List in two halves.

I see an error message "ERROR_DEVELOPMENT_002"!

This message is thrown when no connection to the given synchronization server can be established. Check your network. Reasons may be a wrong ip-address, a flawed WLAN connection or a firewall blocking in your router.

I get the message "Network or server interference occurred"

It's extremely unlikely that our server is the reason, because it's just the same server you just visited with your browser. Please doublecheck your ip-address entered in your SmartHub. ( as of Feb. 2015)

My TV shows the message „request“, but nothing else happens!

Your SmartHub has already established a connection to our server, but fails to finish the synchronization. Be patient - some Apps take a very long time to load. Annother reason may be an incompatibility of one of the selected apps with your TV Model. Find the problematic App by succesively cutting the List in two halves.

Can I synchronize from two different IP-Addresses?

No, when synchronizing from a new ip, all apps synchronized from annother ip will be removed.

I do not find a given App, but I have an own copy of the *.zip Datei!

You can add your own app under Smart-TV-Apps -> "MyApps" and may even share this app with other users. You have to be compliant with our AGBs though, which you accepted when you entered our website.
