Krishna,
Thanks for the quick reply. In our case the issue was as follows:
1. The cert expired and thats when the F5 LB started to choke on external requests (not the internal). Internal requests were served by one ip and the external via another ip.
2. Somehow the CN tied to the site was different than the actual domain name and F5 begin to have issues with that for external requests.
Solution: I regen’d the new cert with the same CN as the name of the domain and restart http. That fixed the issue.
