CirrusAnsible Error: An exception occurred during task execution
Problem solved! At least for us. In short, the module in our playbook needs to be executed on the Big-IP itself which uses Python 2.7 and causes the "split()" error. In most cases this can be resolved with "connection: local" or "delegate_to: localhost", as it is with all the F5 Ansible modules. In our case the solution was a bit different, you can check the GitHub issue for explanation.
CirrusIt is running Python Version 3.8 and BIG IP Version 14.1.2.6.

The problem is our business require traffic to be end to end encrypted for that I am using performanceL4 and after that I am not able to host maintenence page on f5 using iFiles as if I use http profile with perfomanceL4 then it breaks the connection. Is there a way that can be used to host a maintenence page on f5 using iFile.
may this be usable?

Thanks, I see you used when HTTP_REQUEST event in your iRule. The problem is if use this event, than I must have to use HTTP profile with VS which will intern not trigger maintenance page without doing ssl bridging.
The second option I can utilize is hosting maintenance page on an external server and route traffic to that server in case the VS goes down. Not sure if it is possible without SSL bridging.?

there are 2 virtual servers, aren't there? the http profile is in the internal virtual server (i.e. not the external one which is facing users).

Worked perfectly fine !!! Thank you
