Adobe Sign and Power Automate Problems

Help! I am so frustrated. I have been trying for days to set-up a MS Power Automate flow so that completed Adobe Sign documents go to a Sharepoint library. The Sharepoint connection is good, but Adobe Sign keeps giving different errors. First I was getting 'Request Entity Too Large', when trying to log in to the sign in pop up. Now, there is a connection failed icon and it reads "Create and Authorize OAuth connection failed". I have cleared my cookies and cache 5 times. closed all the windows and then reopened them, tried being logged in/logged out in a different browser tab. I have also tried using Chrome and Edge. I have an Enterprise MS account and a Acrobat Pro account with Adobe, I am an admin on both accounts. I don't understand what the problem is and all my days of digging through the support community has not helped me find a solution.
