Digest Authentication Issue with Shelly API in Arduino Project

[Cipro]

I have an Arduino integrated with a few Shelly devices via the API. I retrieve information from the Shelly devices and trigger actions like toggling relays (e.g., http://[IPAddress]/relay/0?turn=toggle). Everything works well until I enable authentication on the Shelly.

Unfortunately, I can't get the digest authentication to work. I have tried implementing it, but I'm still facing issues.

Has anyone successfully implemented Shelly's HTTP digest authentication in an Arduino project? I would greatly appreciate it if you could share the relevant part of the code to help me resolve this.

Thank you so much in advance!
