AMQP disconnects sender links

I'm making an application in Rust to connect to the Azure Iot Hub using AMQP.
I'm able to successfully connect and keep a connection.
But after a few minutes I get this exception:

Detaching sender link "/devices/temperature/messages/events" with error LinkDetached(Some(Error { condition: AmqpError(UnauthorizedAccess), description: Some("Token or Certificate is invalid."), info: Some({Symbol(B:"com.microsoft:is-filtered"): Boolean(true), Symbol(B:"com.microsoft:tracking-id"): String(B:"421ed3f4f4e14c429bf63047c95ef52d-G:0-TimeStamp:01/24/2022 18:38:42")}) }))

Do I need to refresh tokens or credentials, or do something more to keep the sender link up? Im using the Azure Root cert for the initial connection, and I use a self generated Sas-token that is valid for 7 days.

    Hello @Roelens Caleb as per documentation: Communicate with your IoT hub by using the AMQP Protocol | Additional notes

    Your client must occasionally be able to handle link redirections correctly. To understand such an operation, see your AMQP client documentation.

    Then in the code snippet :

    Once a redirect error is received, close the original client and recreate a new one to the re-directed address.

    Let me know if this helps you overcome the issue?

    Thanks!
