Bug description

I have two wordpress container and two domain.

abc.com -> container 1
123.com -> container 2

When I only running the container 1 with domain abc.com, everything works find. And then I start running the container 2 with domain 123.com, the problem happend.

When I access the domain abc.com/contact, it will redirect to 123.com/contact occasionally and vice versa. I also check the network in Chrome developer tool, it will show 301 Moved Permanently and redirect to other domain.

you can't run 2 instances of nginx, that won't work
move the settings from the second app to nginx-proxy's Docker configuration
