ArcGIS Enterprise Sites- adding too many groups seems to break search functionality and the ability to manage groups and content

OsgurMcDermott_Long

I have been creating a sites page on our on premise ArcGIS Enterprise 10.8 however I have been running into the issue that as soon as I add more than about 33 groups the ability to manage groups and content disappears. As does the ability to search for data using the search bar. Clicking " Groups Manager" / "Content Library" or using the search bar returns a 

404

So sorry. We looked everywhere and just can't seem to find what you were looking for.

I can browse to the data I am looking for using the category connections I have set up. 

Any help would be much appreciated!

I believe you can increase the web server's allowance for REST API request size....what I think you're hitting is the query request is exceeding IIS' allowed size for a query (10kb I think is their default). If you bump that number, it may start to work. One useful troubleshooting tool is to look at the failing XHR in your browser's network tab as that'll likely tell us the root cause.
