Erro cabeçalho nextcloud no centos 8

[details=“Support intro”]

In all linux ubuntu versions the HTTP header configuration error “Strict-Transport-Security” is resolved, but in version 8 hundred, this error does not resolve in any way, I have already followed everything that is in the nextcloud support but it does not solve, can you please give a light? it only remains to resolve this matter so that the nextcloud runs without warning of errors.

The HTTP header “Strict-Transport-Security” is not set for at least “15552000” seconds. For added security, it is recommended to activate HSTS as described in the security tips :arrow_upper_right:.
