Bir https sunucusundan bir dosya indirecek bir sınıf var . Ben çalıştırdığımda, birçok hata döndürür. Sertifikamla ilgili bir sorunum var gibi görünüyor. İstemci-sunucu kimlik doğrulamasını yok saymak mümkün mü? Öyleyse nasıl?

Bir keresinde bu hatayı aldım ve güvenlik ekibimizle iletişime geçtim ve takımımız şirket tarafından sağlanan eski bir tanesini kullandığından, kullandığımız JAR'ı düzeltmek zorunda kaldım. Benzer bir durumda olabilecek herkes için sadece bir FYI.
