Problem running workflow: There is already an entry with this name

[arkka]

I’m using n8n Cloud, Pro package.
I’ve noticed that since the end of August 2025, all of my workflows are stop executing.
I’ve tried to restart and upgrade to the latest stable version (1.110.1), but the problem persists.

Whenever I tried to manually start a workflow, it’s always gives same error:

Problem running workflow: There is already an entry with this name.

I’ve double check, and ensure that there are no naming conflict. I’ve even create a new workflow from scratch, but the error is still the same.

Need help on this.

Hey @arkka hope all is well. Welcome to the community.

See if there is any helpful information in what appears to be a very similar issue here:

Cloud Version - Workflow could not be activated: There is already an entry with this name

Describe the issue/error/question In the cloud version it is not allowing me to activate my workflow. I am receiving this error claiming there is an already an entry with this name. Not sure if it is referring to the workflow name but I only have 2 workflows and the names are completely distinct. [n8ncloudactivationerror] It should be noted that I can run “Execute Workflow” and it will listen for the webhook and run correctly, so I am not sure why I cannot activate it? What is the error …

I’ve already previously check on that thread. I’ve tried create workflow from scratch, the problem still persists.
