Connectivity between Wireless controller and access point went down

If connectivity between WLC and AP goes down for sometime, will clients connected to AP's face network disruption? or there is any grace period that client's rest of use(browsing, access) will work.

If you use flex and central authc then endpoint will continue forward traffic until it re-authc and this point it need capwap to wlc for re-authc

If you use local AP then immediately endpoint will face traffic drop

I don't include roaming here as a backup , because then that also must be possible ,

Here re-auth are you referring for endpoints or Access point?
Once capwap is established, after how much time it will re-attempt to established?

Here re-auth are you referring for endpoints or Access point? Endpoints (wifi clients)

Once capwap is established, after how much time it will re-attempt to established? Can you elaborate

This doc was written for AireOS but little has changed on 9800. It details which features can still work in standalone mode:

There's also some discussion in https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-8/FlexConnect_DG.html and the 9800 version of that https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9800-series-wireless-controllers/cat-9800-flexconnect-branch-deployment-guide-og.html
