Authorize.net Sandbox connection issues

evhcbrendan — Wed, 03 May 2017 18:08:12 GMT

Hi Everyone,

I've been using the authorize.net sandbox for awhile now, and I recently ran into a problem where I cannot process test transactions using https://test.authorize.net/gateway/transact.dll. I have my correct transaction ID and key, but I get the same error each time

Unable to finish payment: Payment gateway connection failed.

The Post I am making is going through as a 200, so I was wondering what would cause a gateway connection to fail. I can connect to https://secure2.authorize.net/gateway/transact.dll without any problems, I am only seeing this on test.

I am using Kentico CMS and only recently saw this issue. I haven't seen too many similar issues on online so I came here to see if anyone had any advice for me to troubleshoot. We are using .NET 4.5.2 and IIS, and it is an ASP.net web application.

Does authorize.net block certain connections if they don't meet certain requirements? We have https and ssl on this site.

Is there a place in the test merchant interface to see if these test connections are even reaching my account? I have my account set to Live mode.

Or could it be that the test sandbox down right now?

Thanks

Brendan

Hello @evhcbrendan

Our sandbox now requires TLS 1.2, you'll need to make the necessary changes to ensure you can make a connection.

See our blog post for more information.

Hi Richard

I actually just discovered the same thing! Kentico uses TLS 1.1 by default. Thanks for your reponse, hopefully this post can help some others in the future.

For those of you that use Kentico, Please follow these instructions.
