TFTP Server not working

Hi There
Running Version 8.5.4 (x64 build 1942) - Official Release - 30 May 2019
TFTP seem to be not working for me.

Setup:
Start TFTP Server when Any session connects
Local directories up and download set to the same folder

Symptoms:
When I do a TFTP copy from a Cisco IOS box specifying my laptop IP address the TFTP copy attempt times out as if there is not reply.

Note1 TFTP Log:
Here is what appears in the TFTP log file when I run SecureCRT and connect to a host:

Code:
Thu Jun  3 07:12:28 2021,18700,,Starting server on [::]:69 
Thu Jun  3 07:12:28 2021,18700,,Starting server on 0.0.0.0:69
"0.0.0.0" does not look promising.
Does that signal an issue?

Note2 Wireshark on my laptop:
I run wireshark on my laptop them execute the TFTP copy on my IOS box.
I can see 6 TFTP Read request packets arrive from my IOS box.
No replies going out.

Note3 Laptop firewall:
In my expereicne the fact that wiresahrk is showing the TFTP packets arrive suggests there is no laptop firewall issue.
Agreed?

Note4 Laptop IP address:
I have only one NIC currently with an IP address

Question1
From an old post I type in
type netstat -an | find "69"
But this give an error.
I canot work out the correct syntax.
Might you know what is correct?
Anyway netstat output shows the same as the TFTP log

Question2
Any suggestions how to proceed?

Much appreciate any help
