I am getting Lost Connection to gateway for every 5 minutes when I am working on perspective. The gateway is installed in a server and from my laptop browser when I checked the browser console. It appeared as failed to load resource the server responded with status of 404(). Any Idea about what would be causing this issue and what has to be done ---

I'd usually start with a ping test from the laptop. For Windows `ping -t ` will run until stopped by Ctrl-C. ---

I did them and my laptop pinged server and it ran successfully ---

It might be helpful to know a little more about how the Ignition Gateway is deployed. Is there a load balancer or reverse proxy in front of it? ---

There is no load balancer or reverse proxy. Ignition gateway is installed in a server and designer is used from my system . ---

Understood, that narrows the scope a little. In order to find what is returning that 404/not-found, we'll probably need some more details, specifically the error text from the Console of Designer as well as a snippet of the gateway logs (`logs/wrapper.log` under where your Ignition installation is) if there is relevant output from the same time frame. ---

I will attach two txt files that is wrapper log and console from designer for the same time frame from 10 to 10:30. I think this might help .

Interesting, I'm actually not seeing any 404 errors in the console log; rather, intermittent EOFs and websocket failures. It almost seems like there are intermittent network disconnects between you and where the Ignition Gateway is. 🤔 ---

I would also like to attach images taken from Logs under Diagnostics in Gateway. Let me know if this helps ![Screenshot 2025-11-04 111440](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/4/34ee168c3f518d5c370846723bd4edc0b510a747.jpeg) ![Screenshot 2025-11-04 111337](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/f/5f1576abbb05c46fb07374046412b10d54d811d4.jpeg) ---
