(This issue affects PAN-OS 11.1.6-h3.)
When DoH is enabled for DNS Security, multiple DoH transactions in a single HTTP/1 connection might unexpectedly cause the firewall to crash and reboot.
Workaround: Manually disable DoH support for DNS Security using the set deviceconfig setting dns-over-https enable no CLI command. Alternatively, you can remove the DNS Security configuration used to handle DoH traffic.
