No Response from Authorize.net

[shjablon]

We are using Authorize.Net to process payments for our client on our web application.

Occasionally (reported twice in 3 weeks), the client makes the payment and sees the processing wheel spinning, but then nothing happens - it appears to be a time out. The payment has not gone through.

The next day, the client tries again and it works. 

In one case, the exception reported from the application was "Null response received while processing the transaction".

What could be causing this? What is the best way to debug?  

Thank you

I am having similar issues.  Internal log entries state:

Having same problem. Authorize.net outage? We're unable to connect to Authorize.net to process credit card transactions; it looks like it went down at around 2:30 PM Eastern. Visiting the web site returns an error too, from Cloudflare.
