ItshouldalsobenotedthatSlickStack[ss]isHTTPS-only,andthatHSTSisenabledbydefault,meaningthatHTTPsitesarenotsupported.BecauseOpenSSLgeneratesself-signedcertificates,SlickStack[ss]serversrequireCloudFlaretobeactiveinfrontofyourserverinorderforSSLcertificatestobeproperlyCA-signedandloadedbyyourbrowser,atleastuntilthefirstss-installhasbeencompleted(afterthat,youcanswitchtoCertbot/Let'sEncrypt).
