The page at stitch(.)withgoogle(.)com does not load correctly and instead shows an error message: “La página app-companion-430619.appspot..com ha rechazado la conexión.” It appears that the embedded app companion service is refusing the connection, preventing Stitch from functioning at all. **Steps to reproduce:** 1. Open stitch(.)withgoogle(.)com 2. Attempt to start or access the app 3. The error appears instead of loading the interface **Expected behavior:** Stitch should load normally and allow interaction with the app. **Actual behavior:** The page fails to load and shows a connection refused error. **Additional info:** - Browser: Brave - Extensions disabled - Happens consistently ---

Hey @Kamol, sorry for the inconvenience. To clarify, you will not lose your projects unless you delete them yourself. Could you please try a **hard refresh** of your browser and log back into Stitch? We have checked on our end, and everything appears to be functioning correctly at the moment. ---

Hi @RISHABH_CHAUHAN just adding to this thread that I am also seeing this issue since the last two to three days. What I can notice is that in my Google Workspace account, it doesn’t seem to be working, while the same page in a personal Chrome account and profile seems to be opening fine without issues. ---

Hey @EaiFb, thanks for sharing this! That could definitely be one of the reasons. The team is actively investigating this and we are currently collecting console logs for this “creation failed” error. I’d like to request @Cyber-bota to try disabling your browser extensions, if any, and see if that resolves the issue. This will really help us track down and resolve this error quickly! ---

Hey @BIKRAM_SINGH_BISHT, thanks for reporting this! Could you please try disabling extensions like ad blockers, privacy shields, or dark mode extensions, as they can sometimes block internal Google auth links? Additionally, ensure third-party cookies are allowed for Stitch, since Chrome restricts embedded iframe authentication by default. Finally, check if any network-level tools like corporate VPNs, Pi-hole, NextDNS, or firewalls might be dropping requests to raw `appspot.com` instances. Let me know if any of these help resolve the issue! ---
