### Bug Description
After updating **n8n** to version **1.109.1**, a red pop-up… appears in the bottom right with the warning:
"_**Error connecting to n8n
Could not connect to server. Refresh to try again.**_"

I self-host n8n (as localhost) on Podman on Windows 11.
I installed it using docker-compose.yml, created according to this guide:
[(https://docs.n8n.io/hosting/installation/docker/#prerequisites)]
YAML
```
version: '3.8'
services:
n8n:
build: .
container_name: n8n
restart: unless-stopped

```
Up until version **1.108.2**, everything I used in n8n worked fine.
The warning appeared starting with version **1.109.1**.
Updating to **1.109.2** didn't change anything.
I know someone else is having this problem on Docker:
[(https://community.n8n.io/t/help-needed-docker-on-windows-healthy-backend-listening-but-frontend-fails-with-could-not-connect-401-unauthorized/180811)]
The advice from this post to "Try to set **N8N_PROTOCOL** to **http**" didn't help me :/
### To Reproduce
1. Install n8n on Windows 11 with Podman Engine 5.6.0 as localhost by default.
2. Go to the login page.
3. Check the bottom right corner of the page.
### Expected behavior
Pop-up appears in the bottom right with the warning:
"_**Error connecting to n8n
Could not connect to server. Refresh to try again.**_"
