Hi All,
We are testing Direct Tooling -> B1 Transition of Care -> Paragraph (i)(A) Send using Edge protocol - XDR.
All our test cases were passing till a few days back and they've now stopped working. When we send messages from our Gateway to ETT site, we get the error message that points to "Unable to parse the response from recipient"

<Message>The external XDR returned a malformed response.

On Further digging, we found from our logs that the response is a html page (Tomcat Apache) instead of an expected soap/xml. Log File attached.
Please check your logs and confirm if the response from ETT site has changed over last few days.
