I created a connection in ArcGIS Pro, no errors are returned.
I get "This XML file does not appear to have any style information associated with it" error in a webpage.
This URL returns a single tile:
http://www.geo.com/OGC/OGCInterface?UID=me&PASSWORD=gis&interface=OGCInterface&request=GetMap&versio...
The wms gets a no XML error, any suggestions to resolve this using the OGC API??

Unless you are willing to provide a working link, or an example result file, it is difficult for anyone to comment when they have no idea what exactly the XML contents look like.
How is this related to your other post? (OGC URL is not working - Esri Community). You haven't responded there but seemed to be asking a similar question.
@CS_IBM try connecting to the service using WMS Server connection instead of OGC API server connection. Also, enter username and password in the appropriate text fields in the connection dialog, they cannot be part of the connection url.
