From my onprem Windows 2019 server, i was earlier able to telnet to port 443 on the azure storage blob. We have hub and spoke network connectivity between azure and onprem via az express route.

We have private endpoint for the azure storage blob and we were abel to telnet from onprem server to azure blob storage private IP over port 443.

if i am able to telnet over port 443 to blob IP , then it means i am able to access the blob endpoint.

it was working fine yesterday. Nothing is changed in azure , nor in onprem

But i am not able to telnet to port 443 on azure storage blob.

How do i check the network connectivity between azure storage blob and onprem server?

    Hi,

    How is it connected is it via Expressroute or via Internet? Check local policies on Onpremise firewall whether you are allowed and also for Blob Storage if any changes on the networking to accept connections is from Enabled from selected virtual networks and IP addresses or Disabled?

    Hope this helps.
