Tableau Cloud throws 'invalid server' when saving Snowflake keypair credentials, even though identical embedded credentials work fine and extracts refresh successfully in existing workbooks in Tableau cloud

@DIEGO FERNANDO MARTINEZ RODRIGUEZ

I'm trying to save the snowflake keypair credentials under "Saved Credentials for Data Sources", when i enter the server URL its showing a caution as "Invalid Server".  

Actually the same server "URL" is working fine when i embedded the credentials in tableau desktop and even tried publishing to tableau cloud and extract refresh is also working fine for the embedded credentials.   

Main issue is, i have a workbook in tableau cloud which is live connection for that i need to use the saved credentials. followed the same format

Confused why credentials work fine when embedded with extracts and not as saved credentials. 

Another important observation is, I'm not having any issue with on-premises tableau server, i could save the same keypair credentials without any issue.
