Hi @Natarshia Peck ,
Welcome to Microsoft Q&A forum and thanks for your query.
Could you please check and confirm if both the nodes have same version of Integration Runtime installed? If not please uninstall them and install the latest version of the IR from https://www.microsoft.com/en-us/download/details.aspx?id=39717
Since you are setting up multiple nodes, then you need to make sure they can connect each other through port 8060. It depends on how your network configured. They could be accessible by default in many cases, but also could be restricted in some corporate environment. In most cases you at least need to enable port 8060 for inbound TCP in Windows firewall.
Let us know how it goes.
