Unable to create new host, times out during DHCP setting

Support

Problem: Attempting to create a new host via webGUI. Receive error:

2023-10-12T13:17:34 [E|app|0dd7da93] Failed to save: Create DHCP Settings for foremantest.----.dev task failed with the following error: ERF12-6899 [ProxyAPI::ProxyException]: Unable to set DHCP entry ([RestClient::Exceptions::ReadTimeout]: Timed out reading data from server) for proxy https://----.----.dev:8443/dhcp

Expected outcome: Host creates properly with DHCP set to PXE boot.

Foreman and Proxy versions: 3.7

Distribution and version: Ubuntu 20.04 LTS

Other relevant data:

I have DHCP managed on the server hosting Foreman. I’m not sure if the error indicates there’s a permissions issue where it’s not allowing the DHCP information to be read, or if there needs to be something changed to allow the connection/writing to occur to move forward.

I can share any logs/configs needed to assist in assisting me.

I’ve still been unable to find anything to try to resolve this… any one have advice?

Getting a 504 Gateway Timeout error; however, reviewing the logs still shows the same error occurring.

Tried chmod 755 /etc/dhcp in Ubuntu, and it didn’t fix it…

Hi,did you solve this problem? I meet it also and I don’t know how to deal with it

6

It’s been an extremely long time since I had this issue. I believe it was something in the init templates for provisioning.

7

I use default provisioning template provided by foreman, I think it need to call 8443 proxy to create drug.cfg when add a new host in foreman. But there are some problems in 8443 proxy that foreman couldn’t create the grub.cfg.

Foreman showed read timed out for 8443/dhcp when I confirmed to add a new host in foreman web and awaited foreman to generate cfg

It sounds like you have to get DHCP working appropriately first. My DHCP
worked through to the TFTP stage.
