Hope you can help again.
In short, about 3 months ago I had created a "Search Service Application". It worked.
NOTE: Our SaherPoint 2016 is on the same server as our TFS 2018.
While I was away on vacation, there was an update done to the TFS 2018 databases. After that, the "SEARCH" in SharePoint stopped working. Don't ask me why. I have to clue. Coincidence? Maybe.
Problem is that I have tried everything to fix it. I even deleted the whole "Search Service Application" in Central Admin and nothing doing. This the error I get.
Unable to retrieve topology component health states. This may be because the admin component is not up and running.
Any idea what else I can try.
