With the release of Chrome (and Edge) version 92, a new feature called CECPQ2 was introduced, hardening the TLS 1.3 keychain against brute-force attacks from quantum computers. Unfortunately, this breaks many SSL scanning (IDS) implementations on security appliances (such as firewalls). A workaround is to either temporarily disable scanning or disable CECPQ2 in the browser through a group policy (or registry key).

To turn off CECPQ2 for Chromium, create the following registry keys:

Chrome:

HKEY_LOCAL_MACHINE\Software\Policies\Google\Chrome
"CECPQ2Enabled"=dword:00000000

Edge:

HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Edge
"CECPQ2Enabled"=dword:00000000

A browser restart is sufficient for the change to take effect.
