Hi Saransh, I am going to guess that it has to do with your version of ansible as it appears 2.9 does not yet support IMDS v2, where as latest version (at least 5 and above) doesdoes, as noted in this link: “The module is configured to utilize the session oriented Instance Metadata Service v2 (IMDSv2) [https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html).” [https://docs.ansible.com/ansible/latest/collections/amazon/aws/ec2\_metadata\_facts\_module.html](https://docs.ansible.com/ansible/latest/collections/amazon/aws/ec2_metadata_facts_module.html) [https://docs.ansible.com/ansible/5/collections/amazon/aws/ec2\_metadata\_facts\_module.html](https://docs.ansible.com/ansible/5/collections/amazon/aws/ec2_metadata_facts_module.html) - Rilindo ---

Hi , thanks for the prompt response, I read the article previously as well but was not able to install Ansible to a version of 5 or above because of less available resources. Can you please help in the same. Thanks in advance. ---

You probably won’t be able to upgrade as long as you are using Python 2.7. You will have to figure out a way to get a newer version of Python on the machine if you intend to upgrade to the most recent version of Ansible. - Rilindo ---

Hi Rilindo, As stated by you i upgraded the python version and ansible version as well. Attaching screenshots for the reference. But still the same issue persists in the Metadata fetch. ![Screenshot 2022-07-26 at 8.02.56 AM.png](https://us1.discourse-cdn.com/ansible/original/2X/6/65fb6995129f931bd654e4399d2dd7b0b916c2ac.png) ---

At this point with a supported ansible version, can you paste in the code you were using to query the metadata service? > **(attachments)** > > ![Screenshot 2022-07-26 at 8.02.56 AM.png](https://us1.discourse-cdn.com/ansible/original/2X/6/65fb6995129f931bd654e4399d2dd7b0b916c2ac.png) ---

PFB the used code for checking the IMDS V2 instance. ![Screenshot 2022-07-26 at 8.23.50 AM.png](https://us1.discourse-cdn.com/ansible/original/2X/b/b16c2508af255b2449b57bbccbb0777f78d6e366.png)
