Our users reported that they can’t access to site over HTTPS , from Iran’s ISP’s especially Cellular operators , But they can access without HTTPS ,
We’ve checked and debugged and found that the TLS handshake process Only pass the second one and then connection closes
I know not matter which server config we use , but
Server in Nginx , Certificate LE
and add this one that we have tested with another domain on same server IP and configuration and affected users can access this domain over HTTPS
Is there anything else that we can check ?
