Azure IoT failed acces [401 Unauthorised]

I'm facing a connection issue from my IoT Edge device to its IoT Hub (apparently) as a result of an unauthorised access. This same set-up worked fine under a personal (regular router-ISP) network connection, but failed once set in a larger and more secured network.

I've made sure all necessary ports are open for the device's static IP and connection strings have no typos, but the problem persists. After researching I've found out some users with similar issues had trouble with the SAS authentification, although I've never changed it nor touched it in any of the tests run before, so I'm usure about that one. The logs I'm getting along with the error is the following one:

After the last warning messages it keeps looping checking the edge runtime status and failing to connect, so it never downloads the modules and therefore can't run properly. The device is a raspberry running raspbian.

Any ideas on this issue?

Thanks!

Found the issue, posting here in case anyone comes accross the same problem.

The device couldn't get the date and time automatically so there was a mismatch between this one and Azure's and that caused the authentification error.

Setting the raspberry's date and time to the current one in my region solved the problem.
