I am seeing this same error with Caddy on 25.7.11_2. This is the error from the debug log:
"debug","ts":"2026-01-29T16:51:05Z","logger":"http.log.error.default","msg":"TLS handshake not complete, remote IP cannot be verified","request":{"remote_ip":"192.168.1.1","remote_port":"39822","client_ip":"192.168.1.1","proto":"HTTP/1.1","method":"GET","host":"bonob.wilddev.net","uri":"/","headers":{"Accept":["*/*"],"User-Agent":["curl/8.17.0"]},"tls":{"resumed":false,"version":0,"cipher_suite":0,"proto":"","server_name":""}},"duration":0.00002967,"status":425,"err_id":"a2jmx8j74","err_trace":"caddyhttp.MatchClientIP.MatchWithError (ip_matchers.go:268)"}
I opened an issue with Caddy to see if I can find out more. I did tests using curl and openssl and could not figure out why the 425 is coming back even when using tls 1.2.
