Issue/Introduction
Hi,
We are now seeing a message of "An error occurred while retrieving the list of VSE servers. ." when we login to portal. Here is another error message: "Failed to load data from the virtual service environment: VSE. Make sure that VSE is running. .". The VSE service is running on the server fine.
Not sure what could have caused this, we only changed Java minor version from 1.8.0_261 to 1.8.0_271 on that machine, I checked jre folder under$DEVTEST_HOME and it's pointing to the updated Java version. Here is the log from VSE.log file:
