Hi @apellini,

I tested the following playbook with version 16.1.3.2 without any issue so it's maybe something in your environment.

- hosts: all
  collections:
    - f5networks.f5_modules
  connection: local

  tasks:
     - name: create new UCS in Big-IP device
       f5networks.f5_modules.bigip_ucs_fetch:
         provider:
           server: "X.X.X.X"
           user: "admin"
           password: "mysecret"
           server_port: 443
           validate_certs: no
           no_f5_teem: yes
         src: "bigip16.1.3.2.ucs"
         dest: "/var/tmp/bigip16.1.3.2.ucs"
         async_timeout: 300
       delegate_to: localhost

I have done some test with verbose:

What we could see that UCS is created because on next task remove it from device:

Hi @apellini,

Have you tested with the playbook I provided?
Also are you sure dest is a full path?

[apellini]

Yes. I have launched two times and has worked. We have a strange behaviour with async_timeout at 300 sec, the first time has taken 294 sec and second 632 sec. I was expecting that when 300 sec is reached task gone in failed.

Also consider that we are using 1800 sec as async_timeout because it is needed from other F5.

[pgouband]

Hi @apellini,

Async_timeout is only for ucs creation not the task.
Am I understanding you are able to generate a ucs correctly?

[apellini]

yes but why if I put 1800 sec doesn't work?

[pgouband]

Hi @apellini,

I did the test with 1800 and I have no issue so it's maybe something related to your environment.

[apellini]

But the strangest thing if I put 1800 it fails after 24 min not 30.

Hi @apellini,

Best way to go forward, will be to do a repro with your ucs configuration so you need to open a case via https://my.f5.com
