YAML supports so-called “base-60 floating-point numbers,” which is useful for time calculations.

Therefore, 2222:22 is interpreted as 2222 * 60 + 22, which is 133342.

If the port contains numbers greater than 60, such as 3306:3306 or 8080:80, there is no problem, so this issue doesn’t always occur, making it somewhat obscure.
