If you have to plan an upgrade to last version of conttroller 4.2 or above and you use On Premise controller and EUM Cloud not Eum onPremise behind a corporate proxy,after update and restart of controller EUM will not collect any data due to bug on http library generating on server.log UnknowHostException on agg.appdynamics.com and analytics.api
To workaround this issue create a simple tunnel https
remove entries of proxy host and proxyport from domain.xml
use on linux or windows products like cntlm to auhenticate on real corporate proxy and create a unnel like this
Tunnel 443:agg.eum-appdynamics.com:443
set your controller host file to point to agg.eum-appdynamics.com:443 to a local ip or yor https tunnel server and restart application server
repeat same step for analyticis api if you need using another temporary server on your lan
