Is there any whay that I can get RestSharp to ignore errors in SSL certificates on Windows phone 8? I have a test client, and the service I connect to does not yet have a valid cetificate.
When I make a request now I get the error:
The underlying connection was closed: Could not establish trust
relationship for the SSL/TLS secure channel.
Thanks in advance

I have a web application that I made to connect to my Exchange EWS that mainly looks at a user's Outlook categories. Not sure what changed recently but when connecting, the webpage outputs the following error - Error: The request failed. The underlying connection was closed: An unexpected error occurred on a send.
Where can I begin troubleshooting this error?
I had to update my httpRuntime targetFramework to
The server no longer accepts anything but tls 1.2 and the target framework as set to 4.5 which doesn't support tls by default.
I have my MySQL instance configured to use TLS. I have verified this by intentionally using untrusted certificates and watching the clients fail to connect (with an appropriate error message) and then restarting the MySQL service with trusted certificates configured and having the clients connect successfully.
I wanted to do a final check using openssl's s_client but I can't get it to work. When I execute the command below, I get an error saying "SSL23_GET_SERVER_Hello:unknown protocol" followed by "no peer certificate available" followed by some more text. However, when I use the same command against a TLS-enabled Tomcat instance and against the Remote Desktop port, I am able to establish the connection and view the server's certificate. What am I doing wrong? Does MySQL do some extra pre-negotiation before the TLS handshake starts?
openssl s_client -showcerts -connect host:port
While MySQL may use TLS, it isn't the total outside layer. There is a small amount of preamble that occurs before TLS starts. The openssl command line isn't aware of this.
Use the mysql client with its TLS options to test the client certificate.
I marked the response from #danblack correct as he did answer the question. However, I want to provide more information in case it helps anyone else. The
small amount of preamble that occurs before TLS starts
that he refers to can be found on GitHub here.
I need to evaluate notification functionality in confluence.
I have installed confluence locally on my PC.
I have configured mail server in it by going to General Configuration->Mail Servers->Add a new SMTP mail server
I have provided smtp.office365.com as Server Host Name and 587 as Server port.
I have used my company user id as User name and corresponding password.
However when I try to send a test mail, it fails with below exception
"Caused by: javax.mail.MessagingException: Could not connect to SMTP host: smtp.office365.com, port: 587" and also we have tried to configure our smtp server and getting error as "Caused by: java.net.SocketException: Permission denied: connect"
I have seen accepted answers for this question at post https://answers.atlassian.com/questions/139025/error-while-configuring-mail-server
However that is related to a bug Java1.7 whereas I am using Java1.8.
Can someone please suggest any idea what thing can be wrong?
Looking at the hostname it seems that the mail server is in the internet. If you are behind a proxy you will need to configure this in the java options as described here

I am connecting to google geocode web service from .NET code. It works perfectly in my local machine and when deployed in windows 2003 std. server, I am getting the below error.
System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
Where can I get the certificate for Google web service? I tried downloading it from chrome by hitting the url and saved the certificate in a file and added to Trusted certificate store but still having same issue when the site is running.
Any suggestion will be greatly appreciated.
I have started to see an intermittant error when sending email via my application.
System.Net.Mail.SmtpException: Service not available, closing transmission channel. The server response was: 4.4.2 service timed out.
Now obviously it's timing out for some reason, but any ideas as to why this is happening now? This is the first time I've seen it happen.
Some things to check:
has anything on the server side changed? Did the admins add some kind of greylisting, perhaps?
what happens if you connect to the server directly via telnet on port 25?
does this occur from other applications, as well (e.g. your desktop E-mail client) ?
