Eski SSL veya TLS s\u00fcr\u00fcmlerinin kullan\u0131lmas\u0131<\/h3>\n

Sunucu yaln\u0131zca SSL 3.0, TLS 1.0 veya TLS 1.1 gibi art\u0131k g\u00fcvenli kabul edilmeyen protokolleri destekliyorsa modern taray\u0131c\u0131lar ba\u011flant\u0131y\u0131 reddedebilir.<\/p>\n

Eksik ara sertifikalar, hatal\u0131 sertifika zinciri veya yanl\u0131\u015f SSL yap\u0131land\u0131rmalar\u0131 bu hataya neden olabilir.<\/p>\n

Sunucu yap\u0131land\u0131rma hatalar\u0131<\/h3>\n

Apache, Nginx, IIS veya farkl\u0131 web sunucular\u0131ndaki SSL ayarlar\u0131n\u0131n eksik veya yanl\u0131\u015f olmas\u0131 g\u00fcvenli ba\u011flant\u0131y\u0131 engelleyebilir.<\/p>\n

Cloudflare gibi CDN servisleri ile sunucu aras\u0131ndaki SSL modu uyumsuz oldu\u011funda istemci taraf\u0131nda bu hata g\u00f6r\u00fclebilir.<\/p>\n

Eski i\u015fletim sistemi veya taray\u0131c\u0131<\/h3>\n

Nadir durumlarda g\u00fcncel TLS s\u00fcr\u00fcmlerini desteklemeyen eski taray\u0131c\u0131lar veya i\u015fletim sistemleri de ayn\u0131 hata kodunu g\u00f6sterebilir.<\/p>\n
