NextBlock™ CMS Just submitted our application for **NextBlock CMS**! 🚀 NextBlock is an open-source, full-stack CMS framework built natively for **Next.js 16 (App Router + RSC)** and **Supabase (PostgreSQL JSONB)**. We’ve focused on: * **Zero-Config 1-Click Deploy:** Automated Supabase database migrations on build. * **100/100 Lighthouse Defaults:** Tiptap visual editor renders PostgreSQL JSONB directly into React Server Components, eliminating client hydration overhead and HTML sanitization taxes. * **Cortex AI & Native MCP:** Model Context Protocol server support (`/api/mcp`) for deterministic, schema-constrained block synthesis. * **GitHub:** https://github.com/nextblock-cms/nextblock * **Live Sandbox:** https://cms.nextblock.dev Looking forward to the review process and collaborating with the Vercel DX team! 🧱
Axyl1410 Hi! I applied for the Summer 2026 Vercel OSS Program, but I’m not sure whether my application was successfully submitted. I also didn’t receive a confirmation email. Is there any way for applicants to verify whether their application was received, or is there normally no confirmation email after submitting the form? I’d like to avoid submitting a duplicate application if my original submission went through. Thanks!
system There's another community post with 404 debugging tips that might be helpful. Please give these solutions a try and let us know how it goes. https://community.vercel.com/t/debugging-404-errors/437 A human should be around soon to offer more advice. But you can also get helpful information quickly by asking v0.
Joakim 5043 Not helpful.
Joakim 5043 I have now tested the exact documented endpoint: https://mcp.vercel.com Authentication: OAuth. No path or trailing slash. ChatGPT Work still returns: “Dynamic client registration failed: registration endpoint returned 400 (invalid_redirect_uri: The provided redirect URIs are not approved for use by this authorization server.)” The same registration failure therefore occurs on the standard endpoint. Please investigate which callback URI ChatGPT Work submits and why it is rejected. Separately, please verify the authenticated identity and effective team/project permissions behind the existing connector’s 403/404 failures with explicit, verified IDs. Please provide a private channel for any account details or diagnostic information you need.
system The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points. https://vercel.com/docs/domains/troubleshooting
Mclima Thank you for the troubleshooting guide. I reviewed the guide and ran the Vercel connectivity diagnostic as requested by Vercel Support. The diagnostic completed successfully from my location in Portugal. DNS resolution, HTTPS connectivity, the Vercel IP addresses, and the SSL certificate all appear to be working correctly. The issue I am trying to investigate is different from a typical domain configuration problem. The website works normally for me in Portugal, but my friend in McKinney, Texas, has been intermittently unable to access the website. Another person in the same location was also unable to access it. Since the problem appears to be specific to a particular location or network, could someone please advise whether this could be related to Vercel's edge routing, ISP routing, or connectivity to a Vercel IP range from that area? I have the complete diagnostic output available if a Vercel team member needs to review it. Thank you!
