Binance will update the Spot API FIX TLS connection on June 8

Binance announced that it will update the FIX TLS connection for the Spot API on June 8, 2026, at 03:00 (UTC), expected to last about one hour. During the update, existing FIX connections may experience intermittent interruptions.

Binance requests users to confirm that their clients send SNI (Server Name Indication) during the TLS handshake and validate the certificate against the requested hostname before the update. Clients that do not have SNI configured may receive certificate-related error messages during or after the update, leading to TLS handshake or hostname validation failures. Some Node.js clients that do not explicitly configure SNI may be affected.
