Recovery services agent's registration has failed
Currently getting this error when finishing the process to set up the ASR appliance (modernised).
Has anyone seen this before? Any help gratefully received.
Setup of appliance failed as service "Microsoft Azure Recovery Services agent health check failed with error: MT_E_SERVICE_AUTHENTICATION_ERROR (807903300)
App registrations have been created in Azure, however no key vault and the appliance is not appearing under the site infrastructure in the recovery vault.
I have checked that the Azure account being used is an owner of the subscription, so has inhereted rights to create resources etc. in the resource group.
Thanks!
