Apple iPhone won't connect to insecure website
If the certificate has expired, but HSTS is enabled, it is not possible to bypass the error message ‘Safari cannot open the page because it could not establish a secure connection to the server’.



To bypass an expired certificate for a site without HSTS, choose Show Details, then ‘visit this website’.




If the certificate is was revoked, a similar error message is shown but it cannot be bypassed.
