Hi, UweKoch
My personal laptop is also Windows 11, and it seems it is working for me. I have created totally new ngrok account (free subscription) for having a fresh eye as well as cloning the repo from the scratch. I tried wsl2 too, and confirmed it is working too
Can you please confirm if you went through
sign up your ngrok account and setup the authtoken as ngrok - Online in One Line instructed
once you come up to the stage where you successfully install the app to see this screen;
access this ngrok url from your browser, and click the Visit site
Then you will be able to see your descriptor json object successfully. From this point, your macro can successfully render your iframe. Without clicking Visit site, iframe fails to load the iframe html content for free account
If you can’t see the Visit site page, but still getting 6022 error with ngrok url, this is most likely your ngrok auth token issue that you may need to figure out. Perhaps you can try this → Ngrok issue ERR_NGROK_6022 - #5 by tdcardoso
