Unable to connect to sendgrid api via PCF

Issue Summary

We are using the template code below to send email.

Code Snippet

            System.out.println("Sendgrid - building message");
            Email from = new Email(from);
            String subject = "Sending with SendGrid is Fun";
            Email to = new Email(recipient);
            Content content = new Content("text/plain", "Test content");
            Mail mail = new Mail(from, subject, to, content);

            SendGrid sg = new SendGrid(<api_key>);

            Request request = new Request();

            request.setMethod(Method.POST);
            request.setEndpoint("mail/send");
            request.setBody(mail.build());
            Response response = sg.api(request);
            System.out.println("Sendgrid - " + response.getStatusCode());
            System.out.println("Sendgrid - " + response.getBody());
            System.out.println("Sendgrid - " + response.getHeaders());

This works in my local, but when deployed in PCF I get this error

Exception/Log

Is there some sort of configuration needed to be done on the Sendgrid account to allow PCF to send email (vice versa)?

Hi @rubenbasco, thanks for opening an issue. This doesn't seem like a library-specific issue or error, so we encourage you to contact SendGrid Customer Support.
