Unable to connect online (Elden Ring)

Guys, I have such a problem, I can not play with a friend. We do everything as expected, one writes with his finger, the other drinks the potion, and vice versa they tried, neither I nor he sees the call signs. We also tried with passwords for a network game, we also tried without them, and we play other online games without any problems at all, only elden ring puts a spoke in wheels (can anyone tell me what can be done with this?
I have already tried everything and rebooted the Internet, and connected to another Internet, always the same thing (((
