Thank you for your post!
Error Message:
Firewall is turned on and your client IP address is not authorized to access this key vault.... You are unauthorized to view these contents.
I understand that you configured your Key Vault's Firewall to allow public access from a specific VNET and IP address but are having issues accessing your Secrets, even after correctly configuring your Access Policies and adding your IP address to the Firewall. To hopefully point you in the right direction or resolve your issue, I'll share some troubleshooting steps below.
Troubleshooting:
Since you're running into a Key Vault Firewall related error message, you can use your browser's Developer Tool (F12) or you can Capture a Fiddler Trace to see what IP address is being blocked. Once you find the IP address being blocked, you can then add it your KV Firewall as 12.345.678.901 or 12.345.678.0/24
I hope this helps!
