Redirect is not showing from Browser but from F5 CLI

This is an interesting problem. I have a monitor set for https:/FQDN/ouaf with 302 receive string.

there are 2 node 1.1.1.1 1.1.1.2 listening on 6500. Currently on 1.1.1.2 service is down. But both is returning with 302 for /ouaf link. But If I check at IE https://1.1.1.2:6500/ouaf it does not show output meaning service is down.

But from F5 for 1.1.1.2 it returns with 302. Note that there is a redirect policy set from 3.3.3.3 to 3.3.3.3/ouaf ( 3.3.3.3 is the VIP IP )

Question is why for the Service Down Node from F5 it shows 302 but not from browser. ? and how/what to set at monitor in this situation ?

CURL Output from F5
