Deprecating the DHE cipher suite for TLS connections
On Mar 11, 2026 Vercel announced it will remove support for the legacy DHE-RSA-AES256-GCM-SHA384 cipher suite on June 30, 2026. After that date, TLS 1.2 clients that only support this cipher may fail to connect; TLS 1.3 and modern clients are unaffected.
