Start at Pinger.java:73, then inspect HttpProxyCacheServer.java at lines 183 and 82 to trace the failed server check. Reproduce the error using the reported AndroidVideoCache version and determine the network or proxy condition that causes the ping to fail; done means the failure is fixed and covered by an appropriate test.
