ubuntu - Skype - Unable to receive group chat messages

My Skype is working almost completely. I can send files, make and receive calls and chats normally. However, I don't receive messages from chat groups that have been created recently.

What I have tried:

1. remove my ~/.Skype folder;


2. reinstall another version from ubuntu repositories (32 and 64 bits);


3. firewall rules;


4. proxy is fine as other users are successfully talking.

I am on Ubuntu 14.04 64 bits and Skype 4.3.0.37-1 32 bits but this problem seems to happen even on Windows (here and here)

It seems to be related to cloud group chats.

I don't receive messages from groups whose name starts with "19:xxxx". However I receive from groups whose name starts with $ or something else.

The following command returns the group name:

/get name

Answer

I will answer my own question... I hope this will help someone! :)

After struggling a bit, I found some useful commands:

• /dumpmsnp - show details about your connection


• /showplaces - show where you are currently connected

You can execute them in any chat window.

/dumpmsnp command was showing "LoggedOut", but I was online and talking almost normally (except group chats).

System: MSNP: Connection Data:
 * Status: LoggedOut

A lot of people are/were suffering from this problem (here).

To solve this "LoggedOut" issue, try this on any chat window:

/msnp24

and restart your Skype.

After restarting, /dumpmsnp output shows the following status:

System: MSNP: Connection Data (MSNP24):
 * Status: LoggedIn

I don't know exactly why, but the /msnp24 command kinds of converted my account to this protocol and now everything works perfectly.

I've found the solution here.
