bootstrap node stuck on "Install RHCOS"

[LMODEO]

Hi, I'm in the guided exercise to install Openshift, and started with booting Bootstrap node: it should fetch RHCOS image from PXE if I'm correct. However it stays stuck on the PXE initial menu. If I press "tab" looks to me like config is correct. As well as looks to me like tftp config seems ok. Same for httpd.
Any idea how can I troubleshoot this?
Thanks, L.

Hi, I finally got through that, my fault, there was an image missing in http directory path.
Thanks,
L.

I have completed this DO322 course and could complete all the execercises successfully. Now I am setting up a customized home lab for my testing purposes. I am using VMware Workstation Player 17 as Virtualization Software. I configured  everything properly but I am stuck with tftp server. 

TFTP server is running and the client Bootstrap VM is showing error after it got  ip address from DHCP server "unable to get config file. Boot failed". 

SELinux configurations and  Firewall configurations are done same as documentaion. And I checked too. 

But I think still some issues with tftp server. Please see the below output.

Please see more details.

===============================================================

Apart from file contexts shown below any additional SELinux settings are required?

-rwxr-xr-x. 1 root root unconfined_u:object_r:tftpdir_rw_t:s0 622 Jun 29 17:52 00-50-56-3b-d6-70.

Also nmap output is not showing 69/udp status. I think my SELinux port settings are correct. PFB.

[root@utility-00 pxelinux.cfg]# semanage port -l|grep tftp
tftp_port_t tcp 69
tftp_port_t udp 69
[root@utility-00 pxelinux.cfg]#

I have configured both tcp and udp.and in Firewall too both are opened.

====================================================================

What can be the issue? All other services looks fine and tested.

Also may I get RHEL 9 tftp server configuration steps and all the required prerequisites ? I think some difference between RHEL 9 and 8.

Thanks,
