### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description When nginx enables proxy_protocol, and use health `"check type=mysql"`; causes check to fail. Since, per mysql-protocol client expects server params on connect without any transmission from client, However, ProxyProtocol enabled case server expects PROXY v1/v2 header. when nginx enables health check with type=mysql; without protocol header connection attempt is done, which will block for 600s. Effectively deselected for connection from nginx. ### Solution Enable connection to Mysql with and without proxy protocol header; Peek 1 byte data on the channel" - direct connection with not send any data: handle this like normal connection - Proxy connection will send Proxy Header: handle according to proxyHandler - Peeking this data should have a small timeout (~1s), read has 600s default. ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
