Permanent refresh in the GUI

Hello,
i am from Germany and i hope you will unterstand my english.

Home Assiatnt runs on a Raspberry Pi 3B (as Dockerimage).

TasmoAdmin and ESPHome are currently installed (and MQTT (not konfigured yet), and Editor. I already noticed with Tasmoadmin that you have to be very quick when adding new entries. If I take my time, the page refreshes. At the same time, “Connection disconnected, new connection” is displayed in the area of the left bar.

Since I have noticed this with ESPHome, I will call it a general problem. With ESP Home, he then sprints back to the ESPHome start screen, also with the connection information at the bottom left.

Have I configured something wrong or is there another parameter to be set so that it doesn’t seem to break the connection?

I don’t have this phenomenon only on one computer but everywhere, regardless of the browser (Firefox, Chrome).

On the Wibsides i found hints but the Problem was allways an nginx installation. I have no such Modul installed.

If you open the browser console, what do you see?

My Pi ist available on http://192.168.0.34:8123/lovelace.

When i open it in a browser i am in the Overview. on the left is my Laserprinter with the status of the Colors, in the mid my TV and under this ist is the entry Volumio (an other Raspi). AT the right side the Weatherforecast.
in the upper area are 4 Buttons (Updater, RPi Power Status, My Account/User Name/Weather)

I mean in the browser’s developer tools’ console tab.

Do you mean the /config/configuration.yaml file?

No. Press F12 to open the developer tools of the browser you currently use. Then press the console tab. What do you see there?

No, the browser’s developer tools, not Home Assistant developer tools. Press this button:

Then press this button:

And post a screenshot of anything red.

Can you select it, copy the text, and paste it?

Firefox kann keine Verbindung zu dem Server unter ws://192.168.0.34:8123/api/websocket aufbauen. core.87e3602e.js:1
Diese Website verwendet anscheinend einen scroll-verknüpften Positionierungseffekt. Dies könnte mit asynchronem Verschieben (Panning) schlecht zusammenspielen; siehe https://developer.mozilla.org/docs/Mozilla/Performance/ScrollLinkedEffects für weitere Details und nehmen Sie an der Diskussion über damit verbundene Werkzeuge und Funktionen teil! state

Now go to the page where it randomly reloads, and see if anything shows up in the console before, after, and while reloading.

When i in ESP Home Modul aln will konfigure a new one. When the refresh comes these text will appear:

Firefox kann keine Verbindung zu dem Server unter ws://192.168.0.34:8123/api/websocket aufbauen. core.87e3602e.js:1
Passwort-Felder sind in einem unsicheren (http://) Iframe vorhanden. Dies ist ein Sicherheitsrisiko, durch das Zugangsdaten gestohlen werden können.

I don’t know why it can’t connect to the websocket, but that’s one of the problems.

Is it a timeing problem maybe? Is the Raspi 3B to slow?

I don’t know. Does rebooting the Raspberry Pi and restarting the browser fix it?

No, ich have rebooted the Raspi sometimes while i test my modules. But now i have an Error Message where i can look for in the web
