# Troubleshooting

If you do not get the Morpheus boot menu, there are a few things to check:

- First, make sure the filename is correct. It must be `pxelinux.0`
- Next, check the TFTP server is responding by using a TFTP client to get the `pxelinux.0` file from the HPE Morpheus Enterprise server using the same host name as you have configured in the DHCP server configuration. Do this test on a machine on the same network as the machines you are trying to boot using PXE
- Leave the port number as 69 (the default) as this will also check the redirect is working
- If a GET call on the default port does not work, and the client allows (most do) try using port 6969. If this works, then the redirect is wrong
- If it will not work on either, check you can access the HPE Morpheus Enterprise server from the network you are on and also check there are no firewalls between the test network and the HPE Morpheus Enterprise Server
