yinyuncan opened a new issue #6006:
URL: https://github.com/apache/apisix/issues/6006
### Improved or typo fixed.
事情由来：想配置一个tidb的tcp代理 然后发现死活连不上 ，一直报
` Lost connection to MySQL server at 'reading initial communication packet'`
这个是我之前的配置：
```yaml
apisix:
# stream 代理（tcp/udp）
stream_proxy: # TCP/UDP proxy
only: false
tcp: # TCP proxy address list
- 1998
```
这个是请求admin api的配置数据
```
curl http://127.0.0.1:9180/apisix/admin/stream_routes/1 -H "X-API-KEY:
apisix-yimazhinengkeji-2022@" -X PUT -d '
{
"sni": "tidb.xxxx.cn",
"server_port": 1998,
"upstream": {
"nodes": {
"10.0.0.80:4000": 1,
"10.0.0.76:4000": 1,
"10.0.0.74:4000": 1
},
"type": "roundrobin"
}
}'
```
按道理连接命令应该是可以连接上的
`mysql --host=tidb.xxxx.cn --port=1998-u root -p`
结果就是一直报` Lost connection to MySQL server at 'reading initial communication
packet'` 这个问题困扰了我一下午
下班回到家 又经过各种尝试 最终发现只需要把 sni 参数去除就可以正常连接了
我也不太好确定这个问题是否为bug 总之我还是反馈一下吧 总感觉这个坑很容易踩到
### Solution
可以正常代理tcp的配置：
```
curl http://127.0.0.1:9180/apisix/admin/stream_routes/1 -H "X-API-KEY:
apisix-yimazhinengkeji-2022@" -X PUT -d '
{
"server_port": 1998,
"upstream": {
"nodes": {
"10.0.0.80:4000": 1,
"10.0.0.76:4000": 1,
"10.0.0.74:4000": 1
},
"type": "roundrobin"
}
}'
```
