When I try to connect to the community, I get the following error:

"Unable to generate a marketplace token. Please ensure that allow_url_fopen is turned on, or that cURL is enabled on your server."

Since both features are turned on, something else must be blocking the attempt to make the connection. Could this be the firewall? If so, which port must be opened to be able to connect to the community? Or is it another problem.

Any help would be appreciated.
