We are experiencing intermittent failures with DBAmp `RefreshAll` jobs across random tables following our Hyperforce migration.

We engaged DBAmp Support, and their analysis indicates that the HTTP callouts are occasionally returning empty responses with **Query Timeout Exceptions**. They suggested that this could be related to firewall or network configuration issues, particularly due to the expanded range of IP addresses used in Hyperforce.

To address this, we implemented **domain-based whitelisting** rather than IP-based rules, allowing:

- `*.force.com`
- `*.salesforce.com`
- `*.salesforce-setup.com`

Based on the tables we are querying, these domains appear to be appropriate, as per [salesforce help page](https://help.salesforce.com/s/articleView?id=xcloud.setup_domains.htm&type=5).

However, the issue persists intermittently.

Has anyone encountered similar issues post-Hyperforce migration? If so, what was the root cause and resolution? Any guidance or recommendations would be greatly appreciated.

Note:&nbsp;_The Salesforce Org is using custom domain._
