Hi @andrijaperovic ,
I've faced the same issue in my environment (Spinnaker deployed on Azure AKS and configured to use an Azure Storage Account as a persistent storage system).
Please, check the Front50 log and search for a message like this:
c.n.s.front50.model.AzureStorageService : Error encountered attempting to store applications/XXXXX

On my side the issue appeared due to the following Azure storage account configuration:
MyStorageAccount-> Configuration -> Secure transfer required -> true
By configuring this option to false I've solved the problem and Spinnaker gets using the storage account as expected.
At the moment, I'm not interested to configure HTTPS on the Spinnaker side.

Furthermore, check the firewall configuration on the Networking section.

B.R.

Thanks @Sampy84 ! We've gone with s3 now for storage account, but definitely will try this out, appreciate the detailed response.

For anyone still struggling with this issue, I found the resolution was to enable "Blob Public Access". I created the storage account using IaC (as any self-respecting DevOps should) instead of using the cli commands described in the help pages and found that the Terraform default is to disable "Blob Public Access" whilst the cli default is to enable it.
FYI I was able to leave "Require secure transfer for REST API operations" enabled.

This would be a useful addition to the documentation for the Operator, we'll leave this issue open until we have clear guidance on settings require for ABS backing stores.
