Check general connectivity
The site must be able to make outbound HTTPS requests to the relevant services. Hosting firewalls, DNS issues, or security plugins can block these requests.
Vulnerability check
The wpvulnerability.net lookup operates independently of Witte Marketing. A failure there does not automatically mean the Witte Marketing connection is also broken.
External analysis and report
When a Witte Marketing request fails, WM Guard stores a technical error message that can be shown in the interface as the reason.
Monitoring
Check whether the connection still exists, access is granted, and a new key was not generated without reconnecting the remote side.
