We found that running steam in the background fixes the issue

Hi,

Same problem here, i can play with friends on online, but not zombie at all, open port 3074 and 4976, disable firewall and same error

I have the same issues, seems like there's a problem with plutonium instead of everyone here having a common probleme

[aaaAAAh.exe]

limit fps to 200

[Totenkov]

i fixed it by unfollowing my friend (also he to me), then refreshing the page and following back again, then open plutonium and play as normal (We do this process everytime to play, its the only way we found to fix it. (We only tested this on T6 zombies so).

one simple fix just see if your ip address

is not 0.255
if its starts like this just restart your game until it change it
