The extension manager cannot connect to the online gallery from our school network. That might be due to firewall settings, however, there is no specific error message. What access adress/port needs to be enabled (and how is that done)?

Edit: There was a server side problem when the number of installed plugins was too large.

I can only say that our academic network is going through a proxy server. At the time being, I did not note any problem about Online gallery. Actually, I even do not know where to set all this things, as Martin mentioned.

Program needs to have access to smath.info (IP: 188.143.132.211) by HTTP (port: 80).
