[Error] Could not start BO2 - Could not authenticate to Plutonium: handshake: An existing connection was forcibly closed by the remote host

[Plastic Memories]

I'm using Window10 ,and yesterday after 1 game on Nuketown zombie BO2 , I can't start T6 Plutonium anymore

When I clicked on Play button to play Black Ops 2 Zombie , an error window pops up
"Could not authenticate to Plutonium: handshake: An existing connection was forcibly closed by the remote host "

If anyone know how to solve this lease let me know .Thanks

Probably some 3rd party firewall blocking Pluto. What antivirus do you have?

HannesC nothing , and i also have turned off all windows firewall ,defender ...

Turning off AVs is never a good thing, re-enable it and add Pluto to exclusions instead - https://plutonium.pw/docs/antivirus/#how-do-i-fix-this-windows-defender
