You should gradually raise the set::ssl::sts-policy::duration time. This to prevent you inadvertently locking users out due to a misconfiguration:
 * Begin with 5 minutes (5m) during testing.
 * After a week, consider raising it to a day (1d).
 * After a month, consider raising it to it's final setting, such as half a year (180d)
