Is is working fine when you setup the VS as performance layer4 ?

Have you tried the standard VS without http profile attached to it ?

Which F5 version are you running ?

And do you see some error messages while reproducing the issue in "tailf /var/log/ltm" ?

While loading the application in browser do you see CORS error or any other error other than the 404 ?

Hi Abed,

 

We did setup this VIP as a perf layer 4 (without http profile) but that didn't help either. We are running 14.1.2.6 and we don't see any other error message apart from 404 - Resource not found..

    If you setup the f5 on layer4 and still the problem occurs then maybe you're facing what I've faced couple months ago.

    I'm pretty sure you're doing NAT automap , is that so ?

    Then maybe your application is not capable to be accessed from the internal network, from the same subnet network.

    If you have another server on the same backend server network, then try to access your backend server from it.

     

    If this is not the issue, then as   mentioned, check the SNI if your backend is hosting multiple domains.
