I am attempting to add an ArcGIS Server connection using ArcGIS Services with this server URL http://imagery.arcgisonline.com/arcgis/services
This has worked in the past, however, today I receive this error message:
"We were unable to connect to:
Error: Internal server error (status code 500)."
Could someone please help me with this? I need to access this for a college assignment.
You might be facing the issue due to ArcGIS Online's implementation of TLS 1.2 (implemented on April 16, 2019; 9:00 pm PDT).
