Hi to all,
I've just installed concrete5 in our red hat enterprise 5 server.

Then i try to connect to community with my login credentials. I succeeded in sign-in process but then the error message came up:

"Error establishing connection to the concrete5 community. Please check that curl and other required libraries are enabled."

curl is enabled in our php installation. (also "allw_url_fopen" is enabled)

I think "marketplace" connection uses a different ip address or different port/service... I think if i allow this service in firewall configurations rules, the problem will be solved.

Does anyone know this service's port number?
Or do you have another suggestion for my problem?

Thanks a lot since now,
