Why is no longer possible to play Helldivers in the playstation 4? its been 3 or 4 weeks since I get the message that I am unable to reach the servers.
I also tried from the PS VITA, but same result!
It sounds like it is your firewall which may be blocking Helldivers from connecting to the Campaign Backend.
Make sure that any firewall in use is allowing Helldivers to perform outbound connections on port 443.
You might also have to make sure that the firewall is not rejecting self-signed SSL certificates, as this is what the Campaign Backend uses.
