after configuring the people search service in a production environment. and testing it from the end-user side I get this error message on the web when I open the people tab "Oops, something went wrong. an error occurred while loading the directory please try again".
and I get this error message from the hub on the mobile "We are unable to fetch information".and I don't find any KBs related to this issue on the internet.
Note, people's AD sync is working fine without any issues.
Any ideas?
