Hi I'm a newbie to use node-red on raspberry pi and tried to create a simple node is slide show when I deployed and moved to [http://192.168.1.20:1880/ui/](http://192.168.1.20:1880/ui/) but it show "Please add some UI nodes to your flow and redeploy." ![1](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/d/7d4fee99a8eff01809aebf7510d90e3676cada66.png) ![2](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/9/1/91d643427263d0efe88e75de9c02b1ec43a09355.png) ---

You can ignore the loading error. Make sure to disable caching and refresh. ---

I am not sure about chromium, but in chrome, dev tools, network tab, there is a checkbox to disable cache. I believe in developer mode caching is disable by default, then just shift+reload the page. If not, can you show how you configured the dashboard nodes ? ---

Also tell us how you installed node red (did you use the recommended script from the node red docs?), and start node red in a terminal and post the startup log here. Use the`` button when you paste the log in. ---

I installed node-red according to the instructions of [https://nodered.org/docs/getting-started/raspberrypi](https://nodered.org/docs/getting-started/raspberrypi) 1. `sudo apt install build-essential` 2. `bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)` 3. `apt-get install nodered` and use command `sudo systemctl enable nodered` to get startup ---

Good, now show us what you see when you run ```auto node-red-stop node-red-start ``` ---

> [@Percii](#): > > apt-get install nodered You should not have done that. Uninstall it again and run the script again. I don't know whether that is the cause of the problem but it needs to be ruled out. ---

The log looks ok so it probably won't make any difference. It shouldn't mess up your flows though. Are you running the browser on the pi? If so try localhost:1880/ui instead of the ip address. ---

What do you see if you run, in a terminal `ifconfig` Copy/paste the text if possible please. Use the `` button and paste it in. ---

That looks ok, I have no idea why it doesn't work if you use the ip address. Are you using that for the flow editor too? Does it still not work with the ip address? If not then try clearing the cache in the browser, if you haven't already done that. Maybe try a reboot in case Chrome or networking is confused. ---
