When I tried to login in an already configured local environment to WPMUDev Dashboard I got the next error. I used the Bitnami Wordpress Multisite Stack.
Your server had a problem connecting to WPMU DEV: "name lookup timed out". Please try again.
If this problem continues, please contact your host with this error message and ask:
"Is php on my server properly configured to be able to contact https://premium.wpmudev.org/api/dashboard/v1/ with a POST HTTP request via fsockopen or CURL?"
