Workflow always gets stuck: "offer expired" & "found unfinished executions"

Describe the problem/error/question

Hello n8n community,

I’m seeking help with a persistent issue on my self-hosted n8n instance. When I run a specific main workflow (which calls sub-workflows), the execution gets stuck and never finishes.

The logs start filling up with Task (...) rejected by Runner with reason "Offer expired - not accepted within validity window" errors. After some time, the container appears to crash, because on the next startup, the logs show Found unfinished executions.

The most confusing part is that the VM should have more than enough resources. I am running n8n on a Proxmox VM with 6GB of RAM and 4 CPU cores assigned. The workflow itself is not computationally intensive; it mainly consists of simple API requests and a few Code nodes. I don’t believe the hardware resources are the bottleneck.

I have already gone through extensive troubleshooting to rule out infrastructure issues, including:

Cleaning up all old/orphan Docker containers.
Using a clean, minimal docker-compose.yml file.
Resolving all reverse proxy configuration errors.
Upgrading the VM resources to their current state.

Despite all this, the issue persists as soon as I run this specific workload.

PS: Can’t Paste the workflow because of the Formul-Caracter-Limit

What is the error message (if any)?

Did you get any support here? I’m getting the same error (I have my N8N server hosted at Digital Ocean) and until Friday I used it with no issues.

Right now my flows seem to be active and working properly, I just can’t access and edit them.
