Plutonium

I've tried everything in the custom match doc, but none of it works. my pc is my routers dmz, ive port forwarded, my firewall is disabled, and my friend still cant join me. how do i fix it?

My friend always gets a connection error when trying to connect to me by both IP and the Invite feature, not just in bo1 but all plutonium games. I've tried absolutely everything in the "custom matches" post. I tried port forwarding, but it didnt work, upnp also doesnt work. I added my computer to the router DMZ and allow all connections thru firewall and even then my friend still cant join. Please help, i've tried literally everything

First it says "Connecting to online services..." then this
is there any fix for this? i'm not the only one with this problem and this only started happening like 4 days ago. please help. i allowed plutonium thru antivirus and firewall.

HannesC vpn works but its not infinite and not ideal for playing. also this only started happening 3 days ago. i didnt install any windows updates or software that time.

When i press server list or private match, or click on barracks or callsign the game just says "connecting to online services..." for like a minute and then thisIf i press on private match it'll say something about IWnet being down. This issue is already here for like 2 days and im wondering if theres a fix? thanks. version r3266
