Sandbox not working

[dvdaniels]

Attempting to access the sandbox is returning an empty page.

https://test.authorize.net/gateway/transact.dll is the url we have been using for a while. And this is using SIM Hosted page.

I was able to get this on an attempt

Gateway Timeout - In read

Gateway Timeout

The proxy server did not receive a timely response from the upstream server.

Reference #1.c6c18f18.1505416881.13e8a32b

Otherwise it returns an empty html document. 

I know this was working but has stopped recently.

Thanks for any help you may be able to provide.

Hello @dvdaniels

It sounds like your issue is related to a problem other developers reported in this thread:  https://community.developer.authorize.net/t5/Integration-and-Testing/Using-SIM-sandbox-AuthorizeNet-...

I would suggest commenting there as well.

@dvdaniels  I would definitely recommend subscribing to the topic thread that Richard posted for updates, but if you are also able to obtain the http headers from your response, send them over to developer@authorize.net so we can investigate further.
