If web filtering is enabled using a proxy-based firewall policy with SSL inspection also enabled, then connections to servers that still support less secure TLS versions may fail. Browser errors seen: Chrome: ERR_CONNECTION_CLOSED Firefox: PR_END_OF_FILE_ERROR Workaround: toggle affected firewall policies to flow-based inspection. |
