General error: 2006 MySQL server has gone away on a resting WTF server?

Question

MySQL

I ran into a strange thing, I have a MySQL server installed on Windows Server 2019
There is no load on the server (because there is only 1 client there)
From time to time there is such a problem (I suspect that this happens when you do not access mysql for a long time - but this is not a confirmed fact).
The following error pops up:

General error: 2006 MySQL server has gone away

If you repeat the request after a couple of seconds, then everything is ok.

I googled - and all I found is that this error happens when you try to insert a large query with a bunch of data.
But this is absolutely not my case.

For example, my request looks like this:

SELECT
  *
FROM
  `user` t0
WHERE
  t0.m_code = ?
  AND t0.is_verified = ?
LIMIT 1

Data:

"12c9fe68-c781-41a0-b686-9e116e828712", "1"

somehow weakly pulls on a large request, for the base in which there are 2 records ...

Actually, who faced such a thing and how can it be treated?

Answer 1

The muscle breaks the connection by timeout if there are no requests.
There are 2 solutions.
1. Ping the server with simple garbage requests once in a certain period of time.
2. Increase the timeout value in the config. Here it is described how to do it on linux
