Access blob storage account behind on-premise firewall

Question

Im trying to access Azure Blob storage behind an on-premise firewall. I've whitelisted https://(mystorageaccount).blob.core.windows.net and have opened port 443. I'm still not able to upload.
Is there any other site I need to whitelist in order to access blob storage? The firewall is very restrictive and doesnt allow connections except to explicitly whitelisted urls. I saw on another site https://forums.veeam.com/object-storage-f52/used-ports-and-urls-for-azure-blob-storage-t57784.html#top that I might need to whitelist ocsp.msocsp.com to allow my storage client to validate the tls connection but that seems unlikely to me

@bcb44 Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

• Do you get any error message or error code, If so can you please share the screenshot of the error?
• Can you add the specific IP address(Add IP ranges to allow access from the internet or your on-premises networks)

Find the Azure IP Ranges and Service Tags – Public Cloud scope a region where your Azure Storage located. Whitelist the IP list in the storage account firewall

Configure Azure Storage firewalls and virtual networks
Note: NSG to restrict inbound and outbound traffics from this Azure VNet.

Hope this helps!
