Hi Longevillois,
I have same problem with C&C lancher with same error, So I unhook it from C&C launcher and run it normally through origin, it worked online perfectly as I mentioned before but now I have age requirement problem.
To solve your issue do the following :
after you run it through Origin, Then Inside game choose Network >>> Online >>>> then fill up your Revora account credentials as your Email, Password, Nickname and your Age.
But first read common Issues & Solutions here >>> https://forums.revor...sues-solutions/
Open the link then check the third issue at LAUNCHER ISSUES.
Hope that help you
