Cursor IDE
The In-app browser is not opening any website. The browser returns Connection Failed error.
From the tools tab, select “Browser Tab”
In the In-app browse, type the localhost URL. In my case http://localhost:8080
The browser returns Connection failed error
I also tried to open other websites but all the websites are returing same error
Confirmed in Chrome that the localhost:8080 is working and accessible
In-app browser should open localhost website
MacOS
Version: 2.0.38 (Universal)
No - Cursor works, but with this issue

Same experience - tested on Windows 11 with WSL2 and on mac. Same problem with localhost sites.

i am using 2.0.43 and it doesn’t load any website for me.
バージョン: 2.0.43 (system setup)
stopped working for me in the middle of session. LLM was convinced, too, that it was not possible. Despite having solved many issues thanks to it, before.

The chat is unable to interact with the browser. It keeps showing Failed to execute tool browser_snapshot

I have a similar issue when connecting to a database. I need to refresh my credentials but when I click sign in, the cursor embedded browser opens and simply keeps showing a scrollbar thingy in the address bar, but nothing else
