Hello, I'm experiencing a reproducible issue with my custom domain. Custom domain: https://www.detailingtula.ru Deployment domain: https://detailing-datalava-c2w2.vercel.app The deployment domain works perfectly. The custom domain returns the HTML page (HTTP 200), but every static asset request hangs for 30–40 seconds and then fails with ERR_CONNECTION_RESET. Affected resources include: - /_next/static/* - CSS - JavaScript - Fonts - Even /logo.png As a result, the page stays on a black screen because no assets are downloaded. Already tested: - DNS configuration is correct. - SSL certificate is valid. - Created a completely new Vercel project. - Reattached the custom domain. - Redeployed without build cache. - Firewall has no custom rules. - Bot Protection is disabled. - Next.js build succeeds. - The same deployment works perfectly on the .vercel.app domain. The issue reproduces on: - Home ISP - Mobile Internet - VPN The official Vercel connectivity debug script was executed. During diagnostics the following Edge IP ranges were identified: - 216.198.79.x - 64.29.17.x I also found several Community topics describing nearly identical symptoms where the .vercel.app deployment works but the custom domain hangs. Has anyone experienced this recently? Could a Vercel engineer check whether my domain is affected by an Edge routing issue?
