I have been trying to publish a layer to ArcGIS Online but kept failing on multiple ways:
- From arcgis pro (2.4.2)
stuck on "Uploading service definition" and when I stopped the publish, the log shows:

- From arcmap (10.7)
stuck on Server-side post processing...
- From AGOL by uploading csv or shapefile
got the error popup saying: There was an error publishing the service.
The layers are pretty small (about 1k records).
Any thoughts or ways to fix? The service health shows no issues but I am wondering if there is any server side issue.
