Understanding Home Depot Pro Marketplace Connection Resets
Home Depot’s Pro Marketplace supplier portal is hosted on Adobe Commerce Cloud (formerly Magento Commerce Cloud) with Cloudflare as the CDN layer. The portal uses TLS 1.3 with ECH for all authenticated sessions. When suppliers access the portal from macOS Safari on networks with SSL inspection, the ISP gateway resets the ECH-enabled ClientHello, causing the TLS handshake to fail.
Adobe Commerce Cloud’s TLS configuration supports TLS 1.2 fallback, but Cloudflare’s edge policy requires ECH for TLS 1.3 and only falls back to TLS 1.2 when explicitly signaled by the client. ISP gateways that strip the TLS 1.2 signal cause Cloudflare to assume TLS 1.3-only, which fails.
Browser Integrity Sync on Adobe Commerce Cloud
Home Depot’s Pro Marketplace uses browser integrity sync across Adobe Commerce Cloud’s infrastructure. When the TLS handshake is interrupted, the integrity sync fails, and Adobe’s security layer blocks the supplier’s access, requiring re-authentication with a complete TLS handshake.
Fixing Home Depot Pro Marketplace Connection Resets
Using Chrome with TLS 1.2 Forced
Download Chrome → modify the shortcut target to include --tls-max-version=1.2. Launch Chrome and access Home Depot Pro Marketplace. TLS 1.2 does not require ECH, so the handshake completes through ISP gateways that block ECH.
Disabling Corporate Proxy for Home Depot Domains
Configure your network proxy to bypass Home Depot domains. In macOS, navigate to System Settings → Network → Wi-Fi → Details → Proxy. Add *.homedepot.com, *.promarketplace.homedepot.com to the bypass list.
Clearing Browser Cache and Restarting
Open Safari → Clear History → All History. Then Settings → Privacy → Manage Website Data → remove all Home Depot entries. Restart Safari and access the Pro Marketplace portal with a fresh TLS session.
Call to Action
Use the webs.ninja network lab to run a TLS handshake diagnostic for Home Depot’s Pro Marketplace. The diagnostic identifies whether the reset is caused by your ISP’s gateway, a Cloudflare edge node failure, or Home Depot’s Adobe Commerce Cloud infrastructure, directing the fix to the correct layer.
