The Vercel preview URL works fine. This appears to be the same infrastructure issue as [[Production Outage] Custom domains redirect to SafeBrowse](https://community.vercel.com/t/production-outage-custom-domains-redirect-to-safebrowse/29159). ## Project Details * **Working URL:** `tenpo-web-demo-git-main-sam-bonins-projects.vercel.app` * **Broken URL:** `demo.jointenpo.com` * **Other subdomains work:** `staging.jointenpo.com` and `jointenpo.com` work fine ## Symptoms * HTTPS fails with `ERR_SSL_PROTOCOL_ERROR` * HTTP requests redirect to `https://www.safebrowse.io/warn.html` * Vercel dashboard shows **“Valid Configuration”** with green checkmark * SSL certificate was never provisioned ## DNS Configuration ```bash $ dig demo.jointenpo.com +short cname.vercel-dns.com. 76.76.21.123 ``` DNS is correctly pointing to `cname.vercel-dns.com` (same as my working `staging.jointenpo.com` subdomain). ## Edge IPs Returning Errors ```bash 216.150.1.129 216.150.16.129 216.150.1.193 216.150.16.193 ``` These IPs serve plain HTTP redirects to SafeBrowse on port 443 instead of performing a TLS handshake. ## What I’ve Tried 1. Removed and re-added domain multiple times 2. Changed from `CNAME` to `A` record and back 3. Redeployed the project 4. Verified `CAA` records 5. Flushed local DNS cache 6. Waited 12+ hours ## Request Can someone from Vercel infrastructure check why this domain isn’t being routed correctly? Based on thread #29159, this seems to require a server-side fix. Tarlan Isaev (@organicnz) · 2026-02-03 · ♥ 1 Hey @samuelobonin-1406! The issue was resolved by submitting our domain for security review through Google Search Console: https://search.google.com/search-console/security-issues?resource_id=sc-domain:foodshare.club After requesting a review, the SafeBrowse redirects stopped and SSL started working correctly. If you’re experiencing this issue, verify your domain in Search Console and check for any flagged security issues there. > To send your domain to Google Safe Browsing for review, log in to Google Search Console, navigate to Security & Manual Actions > Security Issues, and click "Request a review" after fixing malicious content. Ensure your site is clean, as the review process can take up to 72 hours. Sam Bonin (@samuelobonin-1406) · 2026-02-03 · ♥ 1 Hi @organicnz, Thanks for the helpful recommendation. I was able to use the search console but to my surprise there were no security or manual actions required. There is no were to request a review (likely because of the no flags). I suppose this thread is still pending as I can't solve the issue. Sam Tarlan Isaev (@organicnz) · 2026-02-04 Good luck, Sam! I really hope infra can clear up the SafeBrowse / SSL routing on their side soon. Tarlan Isaev (@organicnz) · 2026-02-04 I’m seeing the same issue on my side now without SafeBrowse redirect. I suspect Vercel is throttling/limiting my project after the “Approaching your limits: Upgrade now to avoid service disruption” warning. Might be time to experiment with Cloudflare Pages lol  Sam Bonin (@samuelobonin-1406) · 2026-02-04 · ♥ 1 @organicnz , do you have Pro account or hobby account? I have pro. Tarlan Isaev (@organicnz) · 2026-02-04 @samuelobonin-1406, I have a Hobby account. Pretty tight on finances since I’m bootstrapping my startup :sweat_smile:
