"Viber service is currently unavailable or being blocked"

Kaser_Soze — Thu, 21 Jun 2012 07:16:33 GMT

I tried to use this app via Wi Fi on my Xperia Arc S, but when I finally managed to link my contacts to viber contacts (it was hard too), I got this when attempting to call someone. Any help would be welcomed.

Try to Restart your device

Does not help. Is it possible that Viber does not support our models?

It supports, i (sometime) used to face the same problem

But restarting was the key for me

Go to settings > applications > all > viber > clear data

Restart your mobile and again open viber but use it with WiFi

Hi,

This is a member of the Viber R&D team.

This probably happens due to your WiFi firewall settings.

Please have the systems administrator go to the WiFi firewall settings to make sure that the below ports are open for both sides:

1) TCP 5242

2) TCP 4244

3) UDP 5243

4) UDP 9785

Please let us know if this works.

Thanks,

Viber team

I tried all the responses from above. I don't know how to fix wifi block problems. I am in US and using T-mobile. I already called T-mobile for the problem. They said they did not block anything.

Hi,

Viber system is currently experiencing connectivity issues. This is related to our hosting provider (Amazon) that is having a major problem that also affects many other services worldwide.

Amazon is on it, and we hope that with their help we'll be able to restore Viber's service soon.

We apologize for the temporary inconvenience.

Good day. I just installed the application on my samsung galaxy tab 2 P5100 and I got the same error. I cleared the data and restarted the tablet but that didn't solve the problem. I'm about to try add the ports to the permitted list in my router but I thought I'd ask you about your service in my country.

I live in the United Arab Emirates and I use DU as my service provider. Du hasn't blocked skype. I can make phone calls but the voice quality is really bad at times. So I wanted to try your application. I got the activation code and verified it while using Du mobile data package.

Is the problem that Amazon is facing affecting the service in my country? Shall I go ahead and do the ports solution or it's no use because the service itself is having issues so it's not matter of which ports are open and which aren't?

Thank you.

Hi @wildheart25c -

The authorities in the UAE have decided to block Viber in the whole country, and that is why you are experiencing this issue. Unfortunately there is not much we can do to help

Try contacting the authorities and ask for the reason for this block.

Hi,

Some mobile operators across the world block Viber on their 3G network. Usually this happens when users have a "simple" data plan (or a prepaid contract), meaning they didn't pay extra for using VoIP on their 3G network.

In order to verify this, we recommend to:

1. Test Viber on a few different WiFi networks, and see that it works fine.

2. Contact your cell company and confirm this with them.

I have a strange problem. I have two SonyEricsson Live phones, one of them have access to viber and one of them have not. and the one does not connect says "Viber service is currently unavailable or..."

both of them connect to the same wifi access point in my apartment.

Re: "Viber service is currently unavailable or being blocked"

viber_team — Tue, 26 Mar 2013 10:57:03 GMT

Hi @ali_tk -

Which two Sony Ericsson devices are these?

Have you made sure that Viber is officially compatible with them? (otherwise, this could be the source of the problem).

Re: "Viber service is currently unavailable or being blocked"

ali_tk — Tue, 26 Mar 2013 11:15:25 GMT

these two are "Sony Ericsson Live with Walkman" and they are officially compatible with viber and they have Android OS, v2.3

Re: "Viber service is currently unavailable or being blocked"

viber_team — Tue, 26 Mar 2013 11:44:19 GMT

@ali_tk -

Unfortunately they are not

Please take a look at the full list in our official HelpDesk: http://helpme.viber.com/index.php?/Knowledgebase/Article/View/45/3/is-your-android-compatible-with-viber-system-requirements

In addition, we would recommend testing the problamtic device on a few different WiFi networks, and see if the problem is the same on all of them.

Lastly,

It could be that the network you are connected to is blocking Viber's traffic.

1. First, please try uninstalling and reinstalling Viber when connecting to a few different WiFi networks (in order to pinpoint the source of the problem). What are the results?

2. Also, please make sure the following ports are enabled ("forwarded") on your routers or firewalls:

TCP: 5242 + 4244

UDP: 5243 + 9785

(if you are not sure how to enable ports, you may contact your router manufacturer)

However, again, if all still fails, please bear in mind that we will not be able to assist you any further, since Viber does not fully support your device.
