Often, my dashboard does not update correctly on my browser. Mostly, background color changes, text changes, and font size do not update.

Refreshing the browser helps some, but not all differences are corrected.

Restarting Node-Red always shows the correct dashboards, but after some time, the browser dashboard again is not correct.

I have tried deleting the browser cache, no improvement.

I have tried different browsers and PCs, Windows 10 Pro, Mac OS Big Sur, Safari, Chrome, MS Edge......all behave the same as described above.

Here is the config:

- Node-Red v1.2.9
- MacPro 2.6 GHz 6-Core Intel Core i7, 32 GB Ram
- Intel NUC six core i7, 32 GB RAM
- Raspberry Pi four, 4 GB RAM, 128 GB USB boot disk

The Raspberry Pi CPU load usually peaks at 25% and average is 10%.

Question - Any suggestions or ideas on what to change to allow my browser to update the Node-Red Dashboard?

Can you show us the startup log from node-red please.

Have you added any customisation of the dashboard or widgets using CSS?

Hi Colin

No customization. Most of the issues are with the "ui\_button", where I use functions to change the background, color and label. Also, I adjust the font size, on the label using.  
"{{label}}"

I did a "node-red-restart" and below is the log:

The font size comment did not go thru. I guess it was removed by the browser.

Again, I adjust the font size and text on the "ui\_button" using:

left carrot font size = 5 right carrot {{label}}

Where left carrot and right carrot are the symbols for same.

Can you do  
`node-red-stop`  
`node-red-start`  
instead please, so you can get the full log. I would suggest tracking down all those errors too.

That is the forum interpreting it. Use this technique when posting flows, code or logs to stop it being messed with - [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

Log below as you requested.

Regarding the error messages, I have. number of devices that send UDP broadcasts to Node-Red. Some of the devices are not always "on" so, Node-Red throws error messages when various nodes do not see the strings or json is missing. I need to add "catch" nodes to those flows to clean up the console.

Here is the log as you requested:

I would start by sorting all those errors. It may not appear that they are relevant but if something you can't explain is happening, and there are issues that you _can_ address then sort those first. Worry about the unexplained issue once you have sorted those out.

Thanks, Nick

Will do. I will take action to remove the cause of errors and report back on the Dashboard stability.

I eliminated the source of the error messages, ran the dashboard overnight, and all continues to be good.

Thanks Colin for your help.
