Re: firefox error when proxied through nginx

I am running pgadmin4 in back of nginx. I've following the instructions on setting up nginx as a reverse proxy. I can successfully log in. I can even create pgadmin4 users. However, when I click on the "Play SQL" icon so that I can directly write SQL 

OR if I try to view data from a view or table I get the following error from firefox

---------------

Firefox Can’t Open This Page

To protect your security, datahub.school will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

This is a very surprising error.  It seems that firefox is stopping the action. Any idea on why this is happening? 

And indeed, when I open it in a new window, I get the same error. 

BTW, I did find the note about creating a config_system.py and adding the session cookie variables -- https://www.pgadmin.org/faq/#13  

But this had no effect -- unless I need to rerun setup.py after adding those.
