​
Website Not Loading After Osto Integration

  • DNS Configuration: Confirm that your website’s A record in your DNS settings points correctly to the Osto IP address.
  • SSL Certificate: Verify that a valid SSL certificate has been uploaded and correctly assigned to the domain in Osto.
  • Firewall Rules: Ensure your origin server’s firewall allows inbound traffic from Osto’s IP ranges.
  • Policy Conflicts: Review your Website Protection Policies to ensure they are not overly restrictive and unintentionally blocking legitimate traffic.
  • DNS Propagation: Clear your local DNS cache or wait for DNS changes to fully propagate (this can take up to 24 hours).

​
SSL Certificate Not Applying Correctly

  • Format and Integrity: Ensure the uploaded certificate is in a valid format (.cert, .key, .pem) and is not corrupted.
  • Domain Mismatch: Check that the certificate’s common name (CN) or subject alternative name (SAN) matches the domain/subdomain you are securing.
  • Re-upload: Try re-uploading the certificate and re-assigning it to the website.
  • Expiration Date: Verify that the SSL certificate has not expired.

​
Security Policies Not Applying

  • Correct Assignment: Double-check that the policy is assigned to the correct users, groups, or websites.
  • Changes Saved: Ensure you clicked Save Policy after making changes.
  • Policy Priority: Look for conflicting rules in other policies. In the case of Secure Server Access, a higher-priority policy (lower number) might be overriding your intended rule.

​
Secure Server Connection Issues

  • Agent Installation: Confirm that the installation script was executed correctly on the server without errors.
  • Outbound Firewall Rules: Ensure the secure server’s firewall allows outbound connections to the Osto platform.
  • Access Credentials: Verify that you are using the correct credentials (e.g., SSH key) for the user attempting to connect.
