Symptoms

• After upgrading a Security Gateway, when traffic passes through the Security Gateway acting as an explicit HTTP/HTTPS Proxy (port 8080), websites may load very slowly or only partially.

Cause

A code limitation causes incorrect HTTP/HTTP2 header processing in the proxy, leading to slow, partial, or frozen website loading.

Solution

This problem was fixed. The fix is included in:

• Check Point Quantum R82.10
• Jumbo Hotfix Accumulator for R82 starting from Take 60
• Jumbo Hotfix Accumulator for R81.20 starting from Take 122

If you choose not to upgrade, Check Point can supply a Hotfix. Contact Check Point Support to get a Hotfix for this issue.
