[BUG] Healthcheck generate tcp connection reset by peer on clickhouse server

[lchabert]

Describe the bug When i run clickhouse proxy, whithout any usefull trafic (only heatbeat), it seems tcp session is broken prematuraly. The TCP connection is raised as an error on clickhouse logs. I'm running clickhouse with TLS.

To Reproduce Run a clickhouse server and clickhouse proxy. Do not run any query on client side. Just run the natural chproxy healthchecks.

Expected behavior Probably tcp connection should be closed correctly.

Logs Clickhouse error logs:
