lchpersonal opened a new issue, #12233: URL: https://github.com/apache/apisix/issues/12233
### Description Access an upstream discovered through Eureka service via version 3.12 of apisix, where the Eureka registered address is a domain name: dev-test.com, not an IP address. Access via http://dev-test.com/HJService/info works alone. However, when accessed via apisix, the following error occurs: 2025/05/20 11:10:39 [error] 1470660#1470660: *359 [lua] balancer.lua:388: run(): failed to set server peer [dev-integ-env.k8s.iflyrec.com:80] err: no host allowed while connecting to upstream, client: 10.10.120.117, server: _, request: "GET /HJService/info HTTP/1.1", host: "172.30.94.83:9080" dns resolve worked good： nslookup dev-integ-env.k8s.iflyrec.com 10.255.255.88 Server: 10.255.255.88 Address: 10.255.255.88#53 Non-authoritative answer: Name: dev-integ-env.k8s.iflyrec.com Address: 172.30.9.198 I tried modifying eureka/init.lua, adding logic for domain name resolution to IP addresses. The process worked, but I found another issue: the forwarded request cannot carry the original domain name of the service discovery target node. how to resolve this problem? ### Environment - APISIX version (run `apisix version`): 3.12 - Operating system (run `uname -a`): Linux 172.30.94.83 5.10.0-60.18.0.50.oe2203.x86_64 #1 SMP Wed Mar 30 03:12:24 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): openresty/1.27.1.1 - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`): etcd_version":"3.4.0 - APISIX Dashboard version, if relevant: - Plugin runner version, for issues related to plugin runners: - LuaRocks version, for installation issues (run `luarocks --version`): -- This is an automated message from the Apache Git Service.
