Hi @Tevon2.0 ,

May I know the version of SharePoint Server you used? Is it SharePoint Server 2019?

According to your description, let's do some troubleshooting:

1, It must be https for both URLs or http for both URLs. It can’t be mixed.

2, Do following steps:

Install the CU of the WFM Client on all of your SharePoint Servers

On the application server hosting Workflow Manager 2013, stop and restart these services:

Service Bus GatewayService

Bus Message Broker

Workflow Manager Backend

Lastly, restart IIS on the WFEs.

3, You can refer to these articles to confirm whether there is a problem with the previous steps.

Hi @Tevon2.0 ,

Have you tried the methods provided in the answer?

If you want to try Power Automate, yes, you can.

To work with Power Automate in SharePoint server 2019, we need to install on-premises gateways and connect to Power Automate cloud then implement the solutions.
For more information on setting up and configuring on-premises data gateway, see:

Hi @Tevon2.0 ,

I found an update for sharepoint workflow manager for your reference:

To ensure users can continue to use SharePoint 2013 platform workflows with their SharePoint Server environments, the SharePoint Product Group has released a new SharePoint Workflow Manager application to replace Service Bus and Microsoft Workflow Manager (Classic WFM). This new workflow application is only designed for SharePoint Server scenarios, and it’s recommended that users switch to this for new and existing Workflow Manager installations.

Users can download the public builds from here: https://www.microsoft.com/en-us/download/details.aspx?id=104867

SharePoint Workflow Manager is compatible with SharePoint 2013, 2016, 2019, and Subscription Edition. We recommend that SharePoint customers replace their existing Microsoft Workflow Manager deployments with SharePoint Workflow Manager once it's released because we'll focus any future investments and maintenance on SharePoint Workflow Manager rather than Microsoft Workflow Manager.
