CKpool Ubuntu installation roadblock

Hi all, I’m trying to install ckpool on Ubuntu and I’ve hit a road block, even ChatGPT can’t help, I run a btc core node on the same pc, Ive configured the conf file on the node and ckpool for the rpc settings but my ckpool still won’t connect to my node, as you can see, it keeps trying to an ip address not associated with my network. Any help would be greatly appreciated and go easy, I’m a complete novice and got to this stage by YouTube videos and ChatGPT. Thanks
