Your project or any libraries may use an unsafe hostname verifier. You may successfully updated this app using the same code without any error on previous time. But it is a new review strategy from google play.
If you are not sure which package is used this unsafe-hostname, you can contact google play support team using the link: https://support.google.com/googleplay/android-developer/contact/app_vuln
Don't forget to select the same Google account to which you have uploaded your project
You will receive an email within 2 or 3 business days with details of this issue, including the name of the library that used the unsafe-hostname.
You can upgrade this library to the latest version, or you can remove this if you are actually not implementing this library in your code.
I got the following detailed email from google when I contacted with the above link. *
For example, your app is currently using the following vulnerable implementation of HostnameVerifier: Llib/android/paypal/com/magnessdk/network/d$1; Llib/android/paypal/com/magnessdk/network/e$1;
My project was not using the PayPal library directly, but paypal is used by another library "braintreepayments". Actually, I am not using this library in my live project, I added this at the initial time of my project. So I commented this library in app/build.gradle, this fixed my issue.
