Postman returns an invalid hostname - soap

Question

I have a web service running on an AWS instance. It can be reached here http://mqlistener-dev.us-east-2.elasticbeanstalk.com/WebService.asmx. When I enter this url into a browser, I am taken to the instance and a page is displayed. This is what I expected to happen. I have code in a c# application which creates a SOAP request and I am able to send that request in and get back a response.
I now want to be able to create the SOAP request from within Postman. I believe I have everything set up, but I keep getting a invalid hostname HTTP error 400 message. This is the CURL code from Postman:
curl --location --request POST 'http://mqlistener-dev.us-east-2.elasticbeanstalk.com/WebService.asmx' \
--header 'SOAPAction: http://jrstestsite.org/mq' \
--header 'Content-Type: text/xml;charset="utf-8"' \
--header 'Accept: text/xml' \
--data-raw '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema- instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<mq xmlns="http://jrstestsite.org/">
<mqRequest> </mqRequest>
</mq>
</soap:Body>
</soap:Envelope>'
Any idea why Postman is not able to reach http://mqlistener-dev.us-east-2.elasticbeanstalk.com/WebService.asmx?
Thank you.
