Workflow 'In progress' Initiator 'Anonymous' Nintex Workflow

[j_aleasa00]

I have an on-prem SharePoint with Nintex workflow. I had an experience a very strange problem with Nintex workflow where I have a number of workflow items that are running well at the beginning but suddenly at some stages of the workflow, the approver faced the common error "Sorry, something went wrong" when he tried to respond to a task. when viewing the workflow we get the following status. Please, a screenshot below:

Looking forward to your help.

Thanks in Advance.

Hi,

I've found a similar issue on a Microsoft forum, referring to the Workflow Service Throttling Limits; https://answers.microsoft.com/en-us/msoffice/forum/all/workflows-not-started-initiator-anonymous/6d1...

I would advise reviewing your workflow configuration to stay below these limits. I hope the hyperlinks mentioned in the answer by Sky Pei are helpful!
