I'm using an HTTP action to call a SOAP request that I have working in Postman, but the HTTP action is giving me a 404...
I've triple checked the URL is the same, and I've copy/pasted the envelope XML body, so I'm not sure why postman can hit that endpoint, but Power Automate is getting a 404.
I've also tried creating a custom connector, and I get the same 404. I know that endpoint is there... what else can I change to get this working??

(working version in Postman)

(postman headers)

(Power Automate 404 failure)
