Azure Blob SFTP Credentials Not Saving in n8n Cloud

I'm trying to connect to Azure Blob SFTP through n8n Cloud, but the credentials save process seems to hang indefinitely. Here are the steps I've taken:

1. Confirmed that SFTP works via my local machine
2. Granted access on Azure Blob for all n8n IPs (refer to Cloud IP addresses | n8n Docs)
3. Created new Credentials on n8n
4. Filled in all details including the SSH password for SFTP
5. Clicked the save button and observed that it remains stuck on “testing” without ever completing

No errors are displayed during this process. The issue appears to be solely with the Credentials setup.

Below is some information about my n8n setup:
