Third party cookie issue in Chrome Incognito. Can not load app. Angular app hosted on nginx server

Topic summary

  • Issue: An Angular app hosted on Nginx fails to load inside a Shopify iframe when accessed in Chrome Incognito, attributed to Chrome’s third‑party cookie policy.

  • Attempts: Cookies were configured with HttpOnly, Secure, and SameSite=None, but this did not resolve the loading problem.

  • Context: The app is embedded via an iframe in Shopify and likely relies on cross‑site (third‑party) cookies for session/auth. Chrome’s Incognito mode imposes stricter rules on third‑party cookies, which can block these cookies and prevent the embedded app from loading.

  • Latest update: Another participant reports having the same issue and asks if a solution was found.

  • Outcome: No fix, workaround, or configuration change has been identified in the thread. The discussion remains open with unanswered questions (e.g., what headers, cookie settings, or alternative auth/session methods would work under Incognito’s restrictions). No logs, code, or screenshots provided.

We have hosted our Angular app on Incognito. Due to Chrome’s third party cookie policy, shopify can not load our app inside iframe on Incognito.

We tried setting cookie policy as httponly, secure and same site none but it did not help us.

Any help would be appreciated.

Do you solve the problem? I have same issue
