Hi, I today installed the latest release of Venus OS Large (version 3.60) in order to get access to Node-RED. However when I try to use any of the Victron nodes, I get errors of the form " Unable to access the service endpoint:/victron/services/input-vebus". This happens for all the Victron nodes. I saw that in for e.g. [Node-RED Victron extension is not working. (node-red-contrib-victron)](https://community.victronenergy.com/t/node-red-victron-extension-is-not-working-node-red-contrib-victron/18019) others have had this issue, but in those cases it seemed users were using a beta (whereas I’ve installed the latest release, not a beta). Any thoughts? Edit: I only have remote access to this Cerbo at the moment and so can’t for e.g. SSH in to check logs. Thanks, Carl ![image](https://europe1.discourse-cdn.com/victron/original/3X/1/3/1335b5654c3a08a028dedf3f5d0b2e3fa32f1f12.png) ---

@mpvader @dfaber any thoughts? It seems like you were able to help resolve this with some of the beta candidates of 3.60 ---

This does happen if there is no _Victron Energy Client_ configuration node. That gets created on the first deploy of a Victron Node. So the way to resolve this is to once deploy with a node on the canvas and thereafter configure it and deploy again. ---

Thanks, @dfaber! Confirmed that solves my problem. Apologies if this is in the documentation somewhere - I’ve been using Node-RED on another Cerbo for years so maybe I’ve just forgotten that this was needed the first time it gets used 🙈 ---

Can you show us again how to do it ? ---

First just pull in the Victron node on to the canvas and click “Deploy” ![image](https://europe1.discourse-cdn.com/victron/original/3X/9/e/9ea7bc0eb619a8c51372fcab3c514475a9b87711.png) ![image](https://europe1.discourse-cdn.com/victron/original/3X/2/c/2c337dced6d545e913c5f48c914d0f4c1c45dc79.png) This will give you a warning, but click “Confirm deploy”. Then, double click the Victron Node and you will get the dropdown for the services. ![image](https://europe1.discourse-cdn.com/victron/original/3X/1/9/19c240dd5ff02eca896bd38c80da1ca6ef644f22.png) After that, click deploy again and the nodes will work (you will only need to do this once). ---

@Grigoriu - add any Victron node to one of your flows and hit Deploy. After you have deployed, when you open the Victron nodes the error should no longer appear. ---

Hi, I have a Multiplus II GX with the last version 3.60 and I have the same problem (Unable to access the service endpoint:/victron/services/…). In Node-red, I run “Deploy” but not solve the problem and the error change to this : _There are no ac load services available. Please check that a ac load is connected or try a different node_ This for “AC Load” but error it’s same with other nodes. In debug window, i have : TypeError: Cannot read properties of undefined (reading ‘name’) ![image](https://europe1.discourse-cdn.com/victron/original/3X/c/c/cc87cd2ddb0a21a8a72751761c6f6dacbd37daa2.png) Have you got an idea ? Thanks ---

@flof: The AC Load doesn’t’ do much as your site doesn’t contain a grid meter that has been configured as AC load. Try the `Ve. Bus System`, `PV Inverter`, `System` or `Settings` nodes, which you do appear to have on your site. ---

Hi, Thanks. Sorry, I have test many node but not this. I would like pilot 2 electric resistor (water and spa) with internal relai k1 et k2. What’s node to use ? I dont see output relay. Regards Flof ---
