Exception: Authentication to host for user using method mysql_native_password failed with message: Reading from the stream has failed (1 reply)

Greetings,

We have a domestic .Net application running at Windows hosts and working with a Centos host with 5.7.19 MySQL DB.
The .Net Connector is 6.8.3.

Occasionally, in various hours of a day, and not every day, the application logs the
"Exception: Authentication to host <myhost> for user <myuser> using method mysql_native_password failed with message: Reading from the stream has failed" messages.

Full message stack is below.

What could be the reason and how to resolve/avoid/workaround the problem ?

Best regards and looking forward the community assistance
