Binance will update Spot API FIX TLS connections on June 8th.

Odaily Planet Daily reports that Binance has announced a FIX TLS connection update for its Spot API on June 8, 2026 at 03:00 (UTC), expected to last approximately one hour. During the update, existing FIX connections may experience intermittent interruptions. Binance requires users to ensure their clients send an SNI (Server Name Indication) during the TLS handshake and verify certificates for the requested hostname before the update. Clients without configured SNI may receive certificate-related error messages during or after the update, causing TLS handshake or hostname verification to fail. Some Node.js clients that do not explicitly configure SNI may be affected.
