Hope you are doing well !
You shouldn't worry about this message, basically the switch is looking for a TFTP server to load the configuration file from the TFTP server but there is no response from the TFTP server so for that reason creates a time out.
The messages can be ignored if the user is not trying to download a configuration file from TFTP server.
If you want that the message disappears you can disable TFTP but you will not be able to do upgrades via TFTP you will have to re-enable it back
