    i have a problem with client's page. He have domain and subdomain For he forced redirect http to https with .htaccess. He have ssl cert only for and

    When we access to apache automaticaly redirect us to and site work perfectly. But when we want to connect from to (by the link), website can not be displayed because of "The connection is not private". In the details of the error we can read something like: "You can not access to this web because of using HSTS"

    At the firts time we thought that the problem was in .htaccess rules, but when we delete him problem was not resolved.

    Interesing is that when we connect directly to first time on each device, website works properly. But when we at first connect to and then connect directly to page show error.

    Headers for and include line:

    Strict-Transport-Security: max-age=10886400; includeSubDomains; preload
    but i have no idea where it is set. Has anyone encountered a similar problem?
