In order to resolve your issue a few more steps of troubleshooting is needed --

 

A VIP or Pool with or without a monitor will still pass traffic. The BIGIP will treats the status as "unknown", where it does not know if the status is UP or DOWN.

 

If you are able to Ping/TCP, did you verify the firewall is not denying the traffic for the Self-IP, if you have "Automap" configured, or the VIP or SNAT IP, if you have a SNAT Pool configured?--TCP will always work if the traffic routes.
