So please help me..

what do you mean by 'the tost error message' ?

Hi, as we enabled the url with SSL it was showing error message unable to connect the server. That I have given in the condition, as this issue was only happening when we are enabling SSL to URL. When I have disabled the SSL in the URL the same app working fine.
I belive the issue is beacuse of the org.apache.http.legacy.jar I don't know how to add another alternative. If you can rewrite/ help me to solve the issue that will be helpful
