I have a client with a Salesforce environment at a custom URL: https://_______.my.salesforce.com, and while I was able to install the Docusign package, I cannot seem to get it to connect to my demo/dev account for the last step of initial setup.
When I'm on Docusign's Connect settings and I use the custom URL option, I get an error that returns with some HTML from the page and no matter what alternate options I select I cannot get it to connect. I have verified that the Docusign IP addresses are set up properly on Salesforce's side to allow access.
Thanks in advance!
