I have Zentyal 3.4 beta installed with only networking modules installed. Several times I notice the following error message:
Corrupted Content Error
The page you are trying to view cannot be shown because an error in the data transmission was detected.

Please contact the website owners to inform them of this problem.
This happens when installing a new module or updating settings through the webgui. It looks like NGinX is acting..... weird...
After the error occured I have to alter the url to
https://ipofzentyal:alternativeport to get back to the Dashboard.
