403 on device subscriptions

Hi!

Another developer working on the same issue with @khelkhelmain.

The code was working for weeks, months.

The current situation is the request to :

https://api.smartthings.com/v1/subscriptions

returns NoContent, and a Subscriptions json, with subid, regurl, name and filters.

The request to connect to the regUrl returns a 403.

The code was running fine one day, and then in the morning started receiving the 403 responses.

We had recently had some adjustments to our API levels and possibly this is related.

Will post requests / responses shortly.
