Extension Import latest version

Hi,
I am trying to change and manage my extension repository under tracktime and i have an issue using the import latest version feature at the extension manager.
I had tested it before on my local test server and it works as supposed, but when i tried to implemented on the live site i get an " There was an error while fetching the requested url " when i try to importat latest versions.

Are there any special server config that can be blocking the updates url???

This is my set up:
Joomla 2.5.11
PHP 5.3.27
TrackTime Pro 2.1.0


Thank you
rgds

Ps. I forgot to mention that i can get regular updates trough the joomla extension manager update.

Ok, understand. I will check my servers config and let you know.

Anyway, There is some kind of bug while getting the extensions. Some of them are saved with a wrong file name what makes unuseable those files without changing the file name and extension.
I attach some screenshots where you will see what i say.

Thanks

you wellcome

Hi again,
I have contacte my host and this is the answer:

The server that hosts you account is protected by a firewall. By default the outgoing connections are disabled. Only port numbers 80 and 443 are allowed. If the extension is trying to initiate an outgoing connection on some other port it will fail. What I would advise you is to contact the developer and ask for more information about the upgrade function. Please ask about the destination IP address and the port used for the connection.

Can you give me more information??

thank you
