I have successfully setup the Java app agent to connect to the saas controller. I can view the BTs, tiers and nodes info from controller. However, when i check the errors in my Application, there are continually says UnknownHostException: risktest.saas.appdynamics.com: Name or service not known. I have check the springboot log, but cannot find such errors. I'm not sure where these exceptions come from. I know it talking about cannot resolve the host, however, i have config the proxyHost and proxyPort during startup. Here is the full stack trace for this exception. java.net.UnknownHostException: java.net.UnknownHostException java.net.Inet4AddressImpl.lookupAllHostAddr(Inet4AddressImpl.java:-2)
