Issues with android devices

My domain is:

My web server is (include version):
Rails with nginx 1.10.3

The operating system my web server runs on is (include version):
Ubuntu 16.04

Nginx config

ssl_protocols TLSv1.2;

ssl_prefer_server_ciphers on;
resolver valid=300s;
resolver_timeout 5s;

ssl_session_cache shared:SSL:50m;
ssl_session_tickets off;

ssl_dhparam /etc/nginx/dhparam.pem;
ssl_session_timeout 1d;

add_header Strict-Transport-Security “max-age=15768000; includeSubdomains;”;
add_header Content-Security-Policy upgrade-insecure-requests;
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;

ssl_stapling on;
ssl_stapling_verify on;

I’ve an active certificate but my website doesn’t work on certain android device due to ssl connection issue, so far the issue appears with android 7 devices like Samsung S8. what do i need to fix this issue ?!

Try using the “intermediate” ciphersuite profile from here:

Still not working :frowning: , is there any solutions ?

Show the exact error, with all details.

Also, did you undo the intermediate profile? Because your server (as of this moment) is still only accepting TLS 1.2 connections, and the intermediate profile should accept 1.0 and 1.1 as well.

@_az yes, i did, now it’s working when i open my app and when i close it and reopen i can’t connect to my server again and that’s happen only with certain carrier and it doesn’t block us !!

the weird thing is that server doesn’t get any requests, and that’s mean that the request has been blocked but i don’t know how or why !

any way to debug and know where’s the problem

Hello is there any updates ? anyone faced such issue ?
