Logic App - When connecting to on prem sql server: The gateway did not receive a response from 'Microsoft.Web' within the specified time period

I have a sql server database which has around 15 stored procedures and 4,73,000 tables. Every month the number of tables gets increased by around 500.

I have created a logic app and added a sql server action to execute a stored procedure which is available in this database. But when I am trying to see if the logic app is pointed to correct stored procedure from the designer view it is giving me the below exception. Also see the below screen shot.

The gateway did not receive a response from 'Microsoft.Web' within the specified time period.

When I verified the logs of on prem data gateway, the below exception is logged there.

Microsoft.Data.Mashup.MashupHostingException (0x80004005): Timeout expired. The timeout period elapsed prior to completion of the operation.

I tried to increase the RAM of the VM to 16GB still having the same issue.

Can anyone help me out is fixing the issue. I am unable to find the cause of the issue as well.

Thanks in advance.
