View Distribution Review 403 & Intermittent Live 403

A 403 error occurs during the deployment preview.

Additionally, a 403 error occurs very intermittently during the live connection as well.

It seems to appear when certain conditions are met; if I open the window in private browsing mode within the same browser, sometimes a 403 appears and sometimes it doesn’t.

The problem is that in environments where a 403 occurs, the error persists.

The issue remains the same even after a hard refresh, and the 403 error continues to occur in the affected environment. However, if I access the site using a different browser, the connection is established.

I have similar issues I have noticed that Vercel’s firewall is blocking “random” IPs including mine and my colleague’s. Today it has been better but yesterday it was more frequent.

I have been also facing same issue

I have exactly the same issue, happens randomly on both production and preview domains. When it happens, only cache clean-up or incognito mode work.

@pawlean does the team know about this issue or should we submit a ticket?
