    Hello! Can you confirm whether port 37 outbound is open on the server? It appears that your server is unable to connect outbound on port 37 to reach rdate.cpanel.net: [2023-07-14 02:38:32 -0500] E [/usr/local/cpanel/scripts/rdate] Can't connect to rdate.cpanel.net:37 Connection refused
    Usually, this error would be caused by port 37 outbound being blocked. I'd recommend ensuring that port 37 outbound is open in your server's firewall, then please let me know if you continue to see errors with the next cPanel update.

    You could run a command such as the following from your server's terminal to see if your server can connect outbound on port 37: # curl portquiz.net:37 Port test successful! Your IP: 1.1.1.1
    If you received a "connection refused" error or something similar from the command, it would indicate that port 37 is blocked. If you are unsure how to open port 37, you can install CSF to help manage your firewall. CSF provides an interface in WHM to help manage the firewall and open/close ports. Although CSF is a third-party product that we do not support, we do have installation instructions you can find below:

    Hello, [QUOTE]the last test of port 37 said "port test successful!". This would indicate that it is open now right?
    Yes, that's correct. I'd recommend either waiting until the next nightly update, or you can run the upcp script manually now to see whether cPanel can update successfully.
