I am having problem from my server's firewall for specific traffic. I have my TFTP server installed in Windows Server 2016 Datacenter for backing up config files from my Cisco switches. So, problem i am experiencing is i can backup config from some of the switches but not from all. The switches are on same network and network firewall has no issue for the traffic.
I enabled the windows firewall but only show if the traffic is allowed or blocked. It does not show why.
Any help, please
