Hi @jakhan33,

Looking at your Schedule configuration, It's not weekly configured but Daily. 😉 Not the problem here. 

To troubleshoot the problem, I suggest the following actions :

• Check the status of the  Nintex Workflow Scheduler Job Timer and the ULS logs for SharePoint to check if there's errors with Workflow Scheduler.  Check all servers that run the Microsoft SharePoint Foundation Workflow Timer Service.
  
  
  
  
  
  • When is the last time the Job Timer ran and succeeded ?

Scheduled Workflows and Nintex Workflow Scheduler job timer

The Nintex Workflow Scheduler Job

• Check the if the publisher and creator are not system account as recommended in the article Scheduled workflows are not starting

• Check with a simple SharePoint Designer workflow with a pausing action and check if you have the same issue which will mean it's a SharePoint native configuration issue.

Hope that helps

^^
