After changing TCP virtual server type from Standard to Performance (HTTP), it might no longer be possible to connect to previously working VIP. The connection to VIP will be silently dropped.
Might not connect to the VIP, and results in the message: 'Connection timed out.'
This occurs when changing a Standard TCP virtual server type to Performance (HTTP).
Change virtual server type from Standard to Performance (Layer 4), then change type from Performance (Layer 4) to Performance (HTTP).
Changing virtual server type from Standard to Performance (HTTP) now works as expected to connect to VIP.
