Hi louiegmd,
Exact same problem as you here.
I have installed bitnami multisite wordpress via google compute but I get that annoying cookies error message every time I try to log in while using Chrome.
I installed Firefox after reading your post and it worked! I could finally log in.
I have made some research on wordpress’ support website as well as on bitnami’s support page but I couldn’t find any solution to our problem.
I’ll be using Firefox for the time being but I wanted to know if you had found a proper solution to that issue.
