GD Security Headers and WP-Rocket problems ?!

hello,

I try many security header plugin, for far this is easiest, complete security header plugin. Many of those that I try don’t work with nginx webserver, this work but… Seems that it have a problem with wp-rocket plugin.

I test it here
https://securityheaders.com/?q=https%3A%2F%2Fbga-rework-stations.com&followRedirects=on

If I clear the cash on wp-rocket first test work like a charm, all is ok, if I try to test consecutively a second, third… and so on tests don’t work. If I clear another time the cash on wp-rocket and test again… work another one fist time test and then don’t work.

Someone encounter this manifestation ?

Best regards, Marcelo
