Hi @adil waaziz,
Based on your query, here is my understanding: I see that you are unable to get PRT for your device and receives the code: 0x800484c0.
Based on the error, we can confirm that you are trying to login to the device using a federated user which throws this error when the IDP is unable to provide token for the device login. This attempt fails when wstrusttokenresponse
fails from the third party IDPs. We have seen many scenarios of the same which occurs due to third party federated IDP's endpoints which are not open or enabled. I would request you to check with your IDP team and check all the ports and endpoints from the IDP are open and available to provide token for device login. There is no issue with Entra here to retrieve PRT for your device.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
