SCIM API authentication failure

I’m attempting to verify a SCIM test application and I’m getting this error when I do so.

I’ve verified that

  • the URL is publicly accessible
  • the runscope tests pass against this url
  • I can use the basic authentication header myself (e.g I can make authenticated requests to the SCIM API)

Are there limitations on subdomains or specific TLDs? Our staging url uses the .fun TLD, and we use subdomains to separate environments, so the base URL could look like this:

I can’t find any kind of request/error details anywhere, even when I look in the logs. Nothing shows the request it sent or the http response code, and nothing is showing up in the logs on my application side.

Can you open a support case, so someone can check our logs for the cause of the error?
