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:
If you see this message, please, report at https://github.com/danikula/AndroidVideoCache/issues/134. Default proxies are: [DIRECT]
com.danikula.videocache.ProxyCacheException: Error pinging server (attempts: 3, max timeout: 280). If you see this message, please, report at https://github.com/danikula/AndroidVideoCache/issues/134. Default proxies are: [DIRECT]. Version: 2.7.1

Start with Pinger.java:73 and trace the reported call path through HttpProxyCacheServer.java and the application's CacheUtil.java at lines 23 and 35. Reproduce the AndroidVideoCache 2.7.1 failure with the reported server and determine the network condition causing the ping to fail; done means a confirmed cause and a verified fix or clear reproduction details.
