In many cases, Safari in iOS 10.2 cannot access websites secured with the "Let's Encrypt" certificate. Instead, unknown error or connection lost is being displayed. Unsecured connections work. In iOS 10.1 both secured and unsecured connections work well. Is Let's Encrypt still supported?
iPhone 5s, iOS 10.2
I'm having a similar issue accessing a site that uses a let's Encrypt certificate...
When I'm connected to wifi the site loads fine on my iPhone, however when it says LTE the site won't load at all. I just get the Safari cannot open the page error.
However, if I'm using wifi and I add the www. to the URL like this...
https://www.talk.peercoin.net/
I get a error message that says Cannot Verify Server Identity. Here is a screenshot...
If I click on details it says Let's Encrypt is "Not Trusted," see another screenshot here...
I've been trying to figure out if this is an issue with the website or if it is an issue with iOS. Any help would be appreciated, thanks!
Me too facing the same issue. Is there anyway to get rid of this issue, without paying for SSL certificate?
Does Apple have any agreements with other certificate providers who charge us for certificates?
This is insane!
Apple do trust Let's Encrypt certificates ( https://community.letsencrypt.org/t/which-browsers-and-operating-systems-support -lets-encrypt/4394 and https://community.letsencrypt.org/t/is-apple-blocking-le-certificates/37640 )
If the connexion is refused it's likely
- An invalid certificate chain ( the server doesn't send the correct certificates chain)
- An invalid ssl/tls configuration
Neither of these problem is because it's a "Let's Encrypt" certificate.
To determine the root cause of the problem the best way it to test the server with https://ssllabs.com : is will display the compatibility of the configuration. If there is a "missing intermediate" warning, the certificate chain must be fixed.
Is that thread helpful for mail: https://community.letsencrypt.org/t/ios-mail-not-trusted/11353?u=tdelmas ?
If not, you should post a message on https://community.letsencrypt.org to explain your problem
Started getting this issue also with all of my websites... Using Lets Encrypt on Ubuntu 14.04 with Apache.
I tested my letsencrypt cert on ssllabs and iOS 10.2 is not tested. The cert works in safari but does not work for mail.
Let's Encrypt not supported in iOS 10.2?
