For the list of server specifications, software, and supported versions see Nintex Gateway Prerequisites.

Required upgrade configuration

The upgrade process to Nintex Gateway v3.3.1 may uninstall and re-install Nintex Gateway on the machine you upgrade. This means the connection to Nintex Workflow will be lost. Once the upgrade is completed and the new version is started, you may be prompted to register against Nintex Workflow again.

Known issues

No known issues at this time.

Resolved issues

• Made a change to the tenant name check to cater for servers that do not respond to HEAD requests. Previously it would have returned an error to say the tenant did not exist, even though it did.

• Identified and fixed a minor security issue.

• Made a change to include additional details for logging exceptions.

New features

The following changes have been made since version 3.0.2 of Nintex Gateway:

• Enhancements have been made to allow better handling and troubleshooting of connection issues.

Resolved issues

• An issue was identified and addressed where Nintex Gateway didn’t log to the event viewer properly. Existing installations are unchanged. The log file locations are also unaffected.

• Added additional check to prevent the on-premises windows service from going down when a response is not received from the azure relay.

Known issues

There were no known issues at this time.

New features

The following changes have been made since version 2.3.2 of Nintex Gateway:

• Support for Nintex Workflow Xtension Custom Connectors using Nintex Gateway / SAP via Theobald.

  • The on-premises windows service has been updated to allow custom connectors/Xtensions to be routed using Nintex Gateway. This allows customers to build custom connectors that can connect securely to on-premises systems. Documentation on how to configure your OpenAPI file is being prepared and will be published soon.

  • This functionality was primarily added to facilitate the integration with Theobald yunIO product which allows Nintex Workflow to integrate with SAP (on premises)

• API Key Management

  • Added APIKey authentication for Nintex Gateway in preparation for the Nintex Kryon RPA connector. This allows connectors to use an API key to authenticate the connection to Nintex Gateway, instead of the Active Directory domain username/password.

  • The ability to manage API keys in the configuration application has been added. Keys are stored security on disk (please consider this for your restore scenario).

• Move to .NET core 6

  • .NET core 3.1 support ends in December 2022

  • The windows service has been upgraded from .NET core 3.1 to .NET core 6.

  • The configuration application has been moved from .NET framework 4.8 to .NET core 6.

  • The tray-icon functionality has been removed due to this change.

Resolved issues

• Logging:

  • The configuration application and windows service now use the same logging framework.

  • The windows service provides a correlation ID in its logfiles, making it easier to track individual requests within the log itself.

• Improved startup stability: Nintex Gateway was not able to handle a situation where there was no internet connection during startup. Nintex Gateway now retries over the course of one minute before shutting down because of no internet connection.

• Improved error handling that caused the Nintex Gateway (windows service) to crash.

• Improvement to the UI of the configuration application with the introduction of a generic error handling screen for unexpected errors.

Known issues

There were no known issues at this time.

The following changes have been made since version 2.2.85 of Nintex Gateway:

• When reconnecting with the same Nintex Gateway hostname, the connection in Nintex Workflow should automatically be updated.

  • When reconnecting from the same computer and/or using the same hostname that was used in a previous disconnected Nintex Gateway connection, The Nintex Workflow connection will be automatically updated to use the newly connected/reconnected Nintex Gateway connection.

• Nintex Workflow Nintex Gateway management page functionality.

  • We have added support for the new Nintex Workflow Nintex Gateway management page. This page can be found on your Nintex Workflow tenant under Settings.

    • Display version number on management page – current installed version of Nintex Gateway (only works with version 2.2.85 and newer).

    • Display status (Online/Offline) – current Nintex Gateway connection status.

The following changes have been made since version 2.2.2 of Nintex Gateway:

• SharePoint Subscription Edition
• We’ve validated that the SharePoint On-Premises functionality also works with SharePoint Server Subscription Edition and have officially added support for this version. No changes have been made for this support.

• Other improvements

  • Various improvements to the error messages and error detection of the on-premises configuration application.

  • Various dependencies updated.

  • Improved error messages in the connection setup within Nintex Workflow.

Resolved issues

• Signed the OnPremises.Gateway.WindowsService.exe. The Gateway Windows Service was previously published as an “Unknown Publisher”.
• Call a Web Service: Amended the Connector to use multiline textbox for header value.
• Call a Web Service: Added regex to header values to only allow ASCII characters less than ASCII character code 127.
• Call a Web Service: Adjusted header value regex to allow numeric values.

Known issues

  • This is a part of a new feature that will be fully implemented in the future.

  • HTTP Methods available: GET, POST, PUT, DELETE, PATCH, OPTIONS, HEAD.

  • The request body can be specified.

  • HTTP Headers can be added and/or overwritten (Host, Content-Length, x-ntx-correlation-id headers cannot be overwritten).

  • The response of the new workflow action is a structured object that gives access to execution details of the Nintex gateway, HTTP Response codes, Headers and body.

• Other improvements

  • Authentication during the registration has been improved with the option to either use manual configuration or to use the Microsoft Edge’s WebView2 implementation. This was needed for a number of issues we’ve encountered. The option for webview2 or manual mode needs to be configured in the configuration file. For the WebView2 option, The runtime will need to be downloaded and installed and then this can be enabled via a configuration option. For more information see Nintex Gateway Troubleshooting.

  • We’ve added a troubleshooting utility to our installation.

Resolved issues

• The configuration application was previously published as an “Unknown Publisher”, this has now been fixed. The Windows Service is still unsigned, which is a known issue.

• The windows service fails to start if network port 5000 is used. We’ve fixed this by finding an open network port automatically. This port is not used for external communication.

• The logic used to validate credentials failed in some AD setups. The logic has been reworked.

• Issues with regards to the filtering options of date/datetime and Microsoft SQL on-premises.

• The SharePoint on-premises connector in Nintex Workflow Cloud did not accept URL’s with a hostname that was not a fully qualified domain name (http://mysharepointsite vs http://mysharepointsite.company.tld).

  • The version number is now shown in the installation wizard.

Resolved issues

• SAM Account validation failure: An issue was identified where the domain\username was not successfully parsed. Please note that this might result in issues if you used the user@domain.tld (principal) notation.

Known issues

• Schema, Tables, Views and stored procedures that have Unicode characters in their name are currently not supported.

• The Nintex Workflow Cloud designer converts the bigint max value from 9223372036854775807 to 9223372036854776000.

  • The Nintex Workflow Cloud designer does not currently support values larger than 9007199254740992. This is less that the maximum range of the SQL BigInt datatype. Trying to input anything larger in the designer can result in a validation failure just before runtime starts. Error parsing fragments: Object must implement IConvertible.

• The Nintex Workflow Cloud designer rounds values after the decimal point so does not allow for specific equals filter scenarios.

• The Create SQL record action will produce and error when using 2079-06-06 23:59:30 on a smalldatetime data type column.

• You are unable to filter on Date, as the Nintex Workflow Cloud designer expects a DateTime.

• You are unable to filter "is on" on DateTime and DateTime2 data type columns.

• In unique disconnect situations, it is possible for Nintex Gateway to leave a workflow in a waiting state that cannot be recovered.

• Columns in SharePoint starting with a special or Unicode character cause an error when used in the condition filter.
