Did something change yesterday? Unable to call remote endpoint

Starting yesterday, when I test my new Alexa skills with the Service Simulator, I get the following Lambda response:

[i]Unable to call remote endpoint or the response is invalid[/i]

And when I test these new skills using my Amazon Echo, the history in my Alexa iPhone app shows the following error:

[i]Unexpected Communication Issue ... There was a problem communicating with the requested application. [/i]

I verified that I set the Event Source of my Lambda functions to Alexa Skills Kit.

Prior to yesterday, everything was working fine.

Not sure if this is related: I noticed yesterday that my Eclipse automatically installed a new version of an AWS plug-in. (My Lambda functions are Java 8.)

Thanks in advance for any assistance!

Hello, The issue that was causing this behavior has been corrected, and all new Lambda Skills should be working as expected. For skills that present the issue; removing and re-adding the Alexa event source should fix the Lambda endpoint. Thanks and once again sorry for the inconvenience,

The AWS plugin updates pretty regularly. I can confirm that it's probably not related.

Thank you, jaquinta. Btw, your book 'How To Program Amazon Echo' has been very helpful!

Even I am facing the very same problem. I have checked everything, from endpoint to ARN, but both the service simulator and the echo are unable to call the lambda function. Its returns with the same message "Unable to call remote endpoint or the response is invalid". When I use the JSON from the service simulator and directly test it on AWS Lambda portal, it works. It seems a communication issue. Any help guys?

The skills that I created yesterday have this problem. The skills that I created prior to yesterday are working fine. I've worked around this problem by pointing my older skills to my new Java classes.

I am having the same issue - but have nothing old to point to. Only new functions....

I am entirely new here, but I am also getting the error "Unable to call remote endpoint or the response is invalid". Same situation in the simulator. No errors on the Lambda functions.

Same issue as well. Older node.js lambda is accessible, but cannot create a new java 8 lambda.
