How to Whitelist IP Addresses With the Security Firewall for ProProfs

If you're seeing issues like courses not loading, login delays, or quiz timeouts, your organization's firewall may be blocking critical IP addresses used by ProProfs. Whitelisting these IP ranges helps avoid access issues and ensures your learners have an uninterrupted training experience.

Why IP Whitelisting Matters

ProProfs Training Maker uses Cloudflare to improve speed and protect data. Cloudflare’s infrastructure uses a dynamic range of IP addresses to deliver secure content quickly. If your firewall blocks these IPs, users may experience:

• Course pages failing to load

• Network errors during video playback or quiz attempts

• Broken SSO or third-party integrations

• Admin dashboard access timing out

These issues can cause training disruptions and affect compliance or onboarding timelines.

Who Should Whitelist These IPs?

Your IT or network security team should review and apply these changes. This is especially important if your organization uses:

• A strict firewall policy or VPN gateway

• Cloud-based tools that require consistent access to embedded content

• API integrations, SSO, or SCORM tracking with external LMS platforms

What to Whitelist

Please whitelist the full range of IPs used by Cloudflare, which ProProfs relies on for secure content delivery.

Make sure to:

• Include both IPv4 and IPv6 addresses

• Allow HTTP and HTTPS traffic on ports 80 and 443

• Apply rules to outbound as well as inbound traffic, if your firewall restricts both

Additional Tips for IT Teams

• Check that no content filtering software or proxies are blocking *.proprofs.com or related subdomains

• If you're using SSO, whitelisting helps maintain a stable connection between ProProfs and your identity provider

• Confirm that your DNS provider does not cache outdated IP records

• Regularly revisit the Cloudflare IP list to update any changed or deprecated entries

What Happens If You Skip This?

If Cloudflare IPs are not whitelisted, your team may report:

• Unexpected logout sessions

• Delays in loading dashboards or reports

• Trouble with learner login, especially during live training

• Missing quiz or course tracking data

These issues can delay completions and interrupt learning paths, especially for compliance or certification-based programs.
