Lets encrypt not working on Android rest api call

I am newly configure ssl certificate. It is working fine in web browser. But based on this https we make rest call in android app. Previously we make rest call using http only. Now we given android update with https enabled but once update the android app not working.

Could you please someone help to resole this…

I believe the problem may stem from the complexities in proper DH cipher implementation.
As shown by SSL Labs results, the server cipher preference order is:

You should try removing the DHE ciphers (or reordering them with lower preferences).

Do you know which Android version(s) have issue?
Do you have a sample of a complete rest API URL that is showing the problem?
Is the rest API URL properly accessible from any non-Android (test) systems?

Do you know which Android version(s) have issue?
Android 7. hope other v6,8,9 working fine. Only some device are facing this issue.

I have some question. Once enable https is it take any time to affect. Because yesterday none of the android version are working but now some device working.

Do you have a sample of a complete rest API URL that is showing the problem?
$.post(“testURL/xxx”,{ xxx : xxx, password : xxxx}, function(data, status){
** // code start here**
});

Is the rest API URL properly accessible from any non-Android (test) systems?
Yes it is working fine . Through web and postman

No; it should happen immediately.

I’m not familiar with Apache-Coyote (Tomcat).
I do not know where/how the ciphers are set.
