I did all the checks on my connection but also with my network provider. they assured me that I have the maximum of services and that everything is working properly. This was something that I knew of course in advance of and use my network successful for other jobs.
My equipment is working properly, I would have noticed it in other games that require online features. I do not find any logic in your reference to the SONY page, to see if any of my equipment has a problem. Nevertheless, I inform you that all my equipment is functional.
To summarize by saying that. I have the digital version for ps5 purchased from the ps store, my connection is fixed and I have talked to my provider, the connection via my router is not via wi-fi but with cable. My equipment is not a problem, I restart the router, I restarted the console, I do uninstall game and I reinstall the console and not an external disk.
My account is not banned. In other games I have multiplayer capability. My NAT type is 2, I changed this from type 3 to type 2 due to another game that was causing me problems. I thought that Nat Type 2 is less strict so it would help it take two, but unfortunately not.
What can I say, I have done all these basics but also advanced ones that you suggest. But I do not see any result. It's supposed to be the title of the year, it's not going to be that hard to be able to play co-op.
