all of these modules rely on the ability for the webserver to make an external httprequest to the 3rd party authentication providers (e.g. facebook etc.) - it appears your webserver does not allow outgoing connections or else some upstream network device such as a router/firewall/proxy is not allowing this. You will have to get this changed or get an exception added to allow for these requests otherwise you cant use these versions of the modules -its possible for some of these providers to use javascript to do the auth check which means server-server requests aren't needed as the requests come from the clients themselves, but I don't know if such versions exist for DNN - unfortunately many providers (facebook in particular) change their javascript based options quite a lot so it was often not a good idea to use those implementations
