Estou testando algumas funcionalidades no servidor. Estava funcionando bem até ontem. Hoje, eles habilitaram o ssl para o servidor (ou seja, de http para https). Agora, quando estou executando meus planos de teste, estou recebendo o seguinte erro. Como posso resolver esse problema.

Embora eu esteja alterando o valor do protocolo para https na minha solicitação, estou recebendo o seguinte erro,

Qual foi o motivo disso? Preciso adicionar alguma coisa na minha solicitação?
