None of the reports are working. Some display a blank chart but others display a blank page.
The issue was coming from the loading timeout.
The Portal needs to wait a little more to get the graph from the jasper server. Most of environment won’t takes more than 10 secs, but the your environment takes more time to get the data. We were able to see the zuul time out error in portal.log
After doing this change the reports are now working:
* Go to DevTest/webserver/phoenix/phoenix-10.1.0/WEB-INF/classes
* Open application.yml file
* Add this lines into the end of the file.
* Restart the portal service.
