Server problems

[Barinjar]

I know I'm not the only one who had and still have this problem, but maybe someone have a solution today. So, my ds2 on any platform that I have: pc (steam), ps3, ps4 losing connection to the servers all the time. Sometimes it works about 30 min, but usually 1-10 min. Any other ds or other fromsoftware game, or any other game that need online works fine. I suppose it's not the problem of game server, because people play normally. Advices like parental control in settings don't work, my connection to the internet is fine. Any ideas how to fix?
