Unless specifically configured to do so via an irule or similar, the BigIP itself will not generate a 504 Gateway Timeout error (or a 429 Too Many Request).

 

So it is most likely that this is an error from one (or all) of the pool members behind the virtual server. This is probably an application issue.

What is your Login behind that 504 and 429 will not be generated by F5 ?

    The LTM isn't a webserver, it's a load balancer. If it cannot get a request to a pool member, the client side connection is reset. If there are too many connections, they get reset or dropped.

    Apart from using an irule to deliberately generate those responses, they just are not responses that the LTM will generate.
