"Template not found" in live-preview I am using docker for my local webdev and am new to Craft CMS.

Currently I have a simple setup running, however, my Live-Preview does not seem to work and throws the "Template not found" error.
Yet, when I surf to the same location in my browser all seems dandy and fine.

I'm sure I'm overlooking something simple, but can't seem to find it.
I needed to set the base-url to @web in:

Settings &gt; Websites &gt; "your Website" &gt; base-url 


This helps on my local docker-environment. Make sure, that your DEFAULT_SITE_URL="domain.something" is set in your .env file and that you are using the latest 3.2.x version.
