Unable to login if I open more than 1 HA-Tabs in my Browser

Installation
1

I am running HA on a Tiny PC with Proxmox.
For Access i Use a Notebook with Linux and the Firefox Browser.

Until ~2 Weeks Ago there was no Problem to open a lot (>20) of HA-Browser Tabs at the same Time.
But 2 Weeks ago the Problem occurred that Home Assistant react “strange” when I opened more Tabs.

First I get the Message “Unable to login” with the Countdown and the “Retry” option.
In some Cases I also get the message, that Home Assistant is not reachable.

HA and my Notebook are in the same LAN even on the same Router.
When the Problems are on my Notebook I can access HA without any Problems from other Devices.
I also can access Local Devices (Shelly f.e.) and websites from my Notebook.

So I think the Problem is between HA and My Notebook.

When I restart the Browser I can work again.

I can rule out the following: I made no new Updates before the Problems started.
So I guess that can’t be the reason.

What I did (without solving the Problem):
Restarted my Router
Updated Linux and Firefox
Deleted Browser-Cache

In the Protocol i found Entries like
Login attempt or request with invalid authentication from ThinkPad (10.0.0.221)
But these entries seems have no connection to the Problems because there is not always such an Entry when the Problem occurred.

So I am at a point where I have no Idea what else I can do or try.
So I am asking for Assistant to find a solution.

Working with this problem is very frustrating because of often loosing progress when the Problem occurs.

?? Why ??

I will have two or three Home Assistant tabs oopen for example when developing an automation in one tab and having the second tab open to the Developer Tools.

I can’t fathom why anyone would have >20 tabs open.

Have you tried a different browser?

Because I often copy from other Dashboards/Automations, develop in Templates, looking for entities and so on.
Often I start another task when noticing something to change.
And so I build up my open Tabs. ^^

You are right, that Isn’t necessary but It’s my “style” to work. ^^

But what I wanted to say is, It worked before.

Yes but it only appears when I am “really” working.
As long I open Tabs randomly for testing it runs fine.
It’s like having a toothache for days but when you go to the dentist nothing hurts anymore. :sweat_smile:

Update:

I have now narrowed down the problem.
It occurs whenever I’m working on my security dashboard.

Among other things, I have the streams from the 12 surveillance cameras there.

I suspect that it has something to do with the frequent updating of the streams that inevitably occurs when editing.

Since the problem occurs with both Firefox and Chrome, I think that it is not a browser problem.

Could it be, that Home Assistant kill the Session for safety reasons if the load/traffic is too high?

Hello @Blueleader72

i am in the same boat but with esphome :

when i want to open more than 1 tab of EspHome, the second and more are blank, nothing inside.

when i modify a node then hit save button, 1 time of 2, it doesnt show the “saved” pop up and doesnt save.
I close the node page and Esphome go back to nodes page and is blank…

it does the same thing with all browser : Firefox, chrome, edge…

i think the problem is with Ingress but i dont know how i could troubleshoot :
