SaaS - Synthetic engines on Windows ActiveGates on v1.289.25 startup issues

We're investigating an issue for Synthetic engines on Windows ActiveGates on v1.289.25 having startup issues on SaaS clusters. We'll provide updates as we determine the next steps.

We've identified an issue with SaaS Windows Synthetic AG version 1.289.25. Rebooting the AG will mitigate the issue. Another possible workaround is to downgrade the AG to the previous version. We're still working on the permanent fix and will continue to provide further updates.

We recommend rebooting the AG to mitigate the issue. The synthetic AG will work as expected then. We’re still investigating the root cause for a permanent fix.
Another workaround is reinstalling the synthetic AG to the previous version and disabling the auto-updates so they don't auto-upgrade again. Note: Rebooting is the recommended mitigation method.

If you continue to experience issues after rebooting the AG, please contact the Support team.

We're still investigating the issue for root cause and recommend following the mitigation steps in the previous update. If you continue to experience issues after rebooting the AG, please contact the Support team.

We're still looking into the matter to pinpoint the root cause and advise following the mitigation steps outlined in the previous update. Should you encounter persisting issues post-reboot of the Active gate, please reach out to our Support team for further assistance.

We have confirmed this issue is caused by 3rd-party anti-malware software in customer's private synthetic AGs, and it is not impacting our public synthetic infrastructure. We are actively working with impacted customers to solve their issues.
