Haproxy dataplane 3.3 : always 404 for runtime API #401
Description
Hi All,
I'm trying to deploy a dataplaneAPI version 3.3 with Haproxy 3.3 and I noticed issues on the runtime response:
# curl -s -u admin:xxx "http://127.0.0.1:9010/v3/services/haproxy/runtime/info" | jq
{
"info": {
"release_date": "0001-01-01"
},
"runtimeAPI": "/data/external/haproxy/run/haproxy.sock"
}
# curl -s -u admin:xxx "http://127.0.0.1:9010/v3/services/haproxy/runtime/backends/grafana-prod-be/servers" | jq
{
"code": 404,
"message": "no data for grafana-prod-be: not found"
}
I configured the logs to debug but I noticed only the access.log
time="2026-02-18T22:49:00+01:00" level=info msg="127.0.0.1 - - [18/Feb/2026:22:49:00 +0100] \"GET /v3/services/haproxy/runtime/info HTTP/1.1\" 200 94 \"-\" \"curl/7.76.1\""
time="2026-02-18T22:49:08+01:00" level=info msg="127.0.0.1 - - [18/Feb/2026:22:49:08 +0100] \"GET /v3/services/haproxy/runtime/backends/grafana-prod-be/servers HTTP/1.1\" 404 64 \"-\" \"curl/7.76.1\""
Could you help me to sort the issue?
Thanks,
Marcello

I think related to #391

Hi, how did you configure HAProxy and the Data Plane API? I had a similar issue that I resolved by carefully checking the CLI options and the HAProxy configuration. I don't think it's a bug.
