Hi.
This problem come from the security layer in Android. It prevents your device to connect to untrusted
SSL certificate.

Maybe your SSL certificate is not valid (on your server) ?

my certificate is from Comodo and it's working from JS socket-io client, and as you mentioned for some other android devices it works well.
what should i do

[MrBin99]

What version of Android do you have on working and non working devices ?
