Error Pinging Server

I am leaving my issue here as told in Logcat. Please tell me the valid solution as I have already tried to add android:usesCleartextTraffic="true" , and android:networkSecurityConfig="@xml/network_config" in manifest file, but still facing same crashing issue.
I am facing below error:
