I'm having an issue where we are intermittently unable to create hosted feature services using ArcGIS Enterprise 11.2 on Windows. This includes creating hosted feature services directly through the Portal UI as well as creating Survey123 forms.
The only error message I receive is: Create Service exception 'java.lang.Exception: Exception: Read timed out'
Survey123 explicitly gives that error message, while Portal gives a generic error message in the web page, but I can see the same error message when viewing the internet traffic. It is a read timed out error, but it usually fails within seconds of attempting to create a hosted feature service.
Esri is not producing any error messages in the Portal, Server, or Data Store logs when this error occurs. This one error message is literally the only error message I'm seeing.
This has happened to multiple people at various times with various hosted feature services/S123 forms, including Esri's template hosted feature services you can create through Portal.
I'm working with Esri support on this one, but does anyone else have any ideas on what this could be? We've already ruled out anti-virus/firewall and the ArcGIS Data Store successfully validates through Server Manager.
