Showing latest lib version

Hi all,
I suspect that my firewall is blocking the update of the version reference for existing libraries. I can actually see just the current version installed.
I'm referring to the latest version of each library which should be displayed in the libraries tab

Any clue on which protocol/port should I allow? Eventually for which executable (if not B4A.exe & co.).
Thank you

The IDE downloads a file from https://www.b4x.com

Make sure that the IDE is allowed to make outgoing connections.

Thank you, Erel.
I added port 51045 to the allowed port list for domain b4x.com and now it works.
I generally allow traffic only on really needed ports..probably a too conservative approach
