v0 blank screen after login preventing access to projects

Problem

I am currently unable to access my v0 workspace. After logging into v0.app (or v0.dev), I am redirected to my project URL ( v0 by Vercel - Build Agents, Apps, and Websites with AI ), but the page remains completely blank.

Troubleshooting Steps Already Taken

  1. Cleared browser cache and cookies.
  2. Disabled all browser extensions.
  3. Tested in Incognito/Private browsing mode.

(None of these steps resolved the issue.)

Account Context & Request

I am a paying user and have spent approximately $300 on this platform. This disruption is heavily impacting my work, and I urgently need to retrieve my project code. Please investigate this issue and advise on a solution as soon as possible.

I’m sorry to hear about this experience. I’ve been unable to replicate it with my own account, have you tried a different browser? I’ll flag this internally anyway.

Update on Troubleshooting & Additional Errors Found:

  • Cross-Browser Issue: I have tested this across multiple different browsers, and the blank screen issue persists on all of them.

  • Primary Request: At this moment, my only priority is to retrieve my project code.

  • New Error Encountered: I also tried accessing it through the Vercel dashboard. When I navigate to the corresponding project in Vercel and click “Open in v0”, the page fails to load and throws the following JSON error: {"error":"Base branch 'main' not found."}

For your reference, the exact URL that triggers this error is: https://v0.app/chat/api/open?vercelProjectId=prj_pnmr01Ihn5sKRDlNvIlRHz6NmR0k&vercelTeamId=team_CYCBty7ONINVgwJmCdCP3WN3&utm_source=vercel-dashboard&gitBranch=main

Same issue here. After login, redirected to /discover-projects/chat but page stays blank.

Key findings from HAR/DevTools:

  1. Redirect loop detected:

    • /chat?scope_fallback=1 → 307 → /discover-projects/chat (repeats 11x)
    • Total 27 requests to /discover-projects/chat endpoint

  2. CSP blocking eval():

    • Console shows: “Content Security Policy of your site blocks the use of ‘eval’ in JavaScript”
    • Blocked resource: VM3725 018jz1_mxx696.js (script-src directive)

  3. No failed HTTP requests – all return 200/307

  4. RSC payloads arrive but React doesn’t hydrate/render

Environment:

  • Browser: [Chrome/Safari Version]
  • Paying subscriber
  • Cleared cache, tested incognito – no change

HAR file available if needed.

Yeah bro, I’m experiencing the exact same situation you described. I have no idea what to do at this point. All I want is to log into my account normally and access my projects.

Same problem here. It seems however only certain accounts are affected, I logged in to v0 with my work account and everything‘s fine, my private account however keeps getting a blank page. This issue has been persistent for the last 24 hrs.

15

my workaroung : enter in the url (ends here with/chat that /1 and hit enter and then click on v0 and all your chats appear

16

Could you please rephrase your answer? I didn‘t quite understand what you mean. I tried replacing ‚/chat‘ with ‚/1‘, but it didn‘t work.

17

not replace add it at the end of the url. so …./chat becomes …./chat/1

18

Thanks, Peter! It worked.

Still, that issue has to be resolved quickly people!

Solution summary

To resolve the v0 blank screen issue, append /1 to the end of the workspace URL (for example, change v0.app/username/chat to v0.app/username/chat/1). This workaround forces the interface to load the chat history and successfully bypasses the redirect loop causing the blank page.
