Intermittent timeout issues when working with hosted feature services in ArcGIS Pro

Description

The attempts to save edits, load tables, or edit hosted feature services in ArcGIS Pro intermittently fail. These intermittent issues prevent local edits from synchronizing successfully with the feature service, affecting operations within ArcGIS Online or the ArcGIS Enterprise portal.

In some instances, the following error returns:

Error:
General function failure [Error code: 1000. Description: Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding. Operation canceled by user.. ]

Cause

The network timeout setting is not configured in the Registry Editor. Therefore, the system does not have a predefined duration to wait for a response from the remote server or service before timing out. Without the configuration, the default timeout behavior is applied, which is insufficient for environments with slow or intermittent network connections. This leads to errors or failed operations when interacting with remote services such as hosted feature services in ArcGIS Pro.

Solution or Workaround

Note:
The following steps involve making changes to the Windows Registry on one or more network machines and require administrative access.

Warning:   
The instructions below include making changes to essential parts of the operating system. Esri recommends backing up the operating system and files, including the registry, before proceeding.

Esri cannot guarantee results from incorrect modifications while following these instructions. Exercise caution. Consult a qualified computer systems professional if necessary.

1. On the Windows taskbar, click Start and type Registry Editor in the search box.
2. Right-click Registry Editor and click Run as administrator. When prompted, click Yes in the User Account Control window.

3. In the Registry Editor window, navigate to the following registry hive:

\HKEY_CURRENT_USER\SOFTWARE\ESRI\ArcGISPro\Settings

4. Right-click the window and select New > DWORD (32-bit) Value.

5. Specify a name for the value. Right-click the newly created value and select Rename to rename the value. In this example, the entry is named 'NetworkTimeout'.

6. Right-click the new entry and select Modify….

7. Configure the parameters in the Edit DWORD (32-bit) Value dialog box.
   1. For Base, select Decimal.
