Timeout while exporting a device state into a TFTP server

Hi,

I'm trying to export a device state from the Panorama CLI into a remote TFTP server, but I get a timeout.
Both the Panorama and the TFTP sever are on the same network, so the traffic does not pass the firewall.
Also, there's over 200 GB of free space on the TFTP server, so the problem is not a lack of space.

What's the reason of the timeout?
The Panorama's IP is xxx.yyy.128.30

The TFTP server's IP is xxx.yyy.128.15
The first three octets are the same.

The command I use is:
tftp export device-state device {serial number} to xxx.yyy.128.15

MobaXterm or Putty shows the Panorama attempting to upload the device-state onto the remote TFTP server, but the connection times out after a few seconds.

Hi @Kfialkowski ,

It doesn't sound like an issue with Panorama. I would first check Layer 3 and Layer 4. Can you reach the TFTP server via ping? Do you have any other clients within the /24 like a windows host or linux host? I would log into one of those clients and run a tcp connection test.

If you have a windows client run the following command to test TCP connectivity:
Test-NetConnection -ComputerName TFTP.Server.IP.Here -Port 69

If you have a linux client run:
telnet TFTP.Server.IP.Here 69

Let me know how the testing goes. What kind of TFTP server do you have? Windows/Linux? If tcp conenctions via 69 are timing out still then id double check if you got a windows defender running or iptables/firewalld running on the server thats blocking the connection.
