There is a network, but it is not (Dark Souls 3)

Hello everyone.
The problem is, the game is online, messages, signs, PVP, everything is there.
One BUT.
I cannot summon phantoms to me, and neither can they invade me.
I see the signs when I summon a phantom, it appears in my world and immediately disappears with the characteristic inscription "Phantom **** has returned home".
The same garbage when I tried to call a friend with a password.
Moreover, they cannot invade me.
it is written that the red phantom invades, I even see it, and a second later it disappears with the same characteristic inscription.
The thing is that it works only in one direction, they can call me, just as I can invade others, but not me.
All Google searched, no hint of such a problem.
There should be no problems with the Internet, all the necessary ports are open, I even tried to connect the Internet directly via a modem (Without a router), it does not help.
Who came across such a persimmon?
Thank you in advance.
