Why Are Workflow Executions Not Displaying in N8N After a VM CPU Upgrade?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I recorded a short 20-second Loom video to demonstrate an issue with my private N8N instance. After upgrading my VM to a higher-tier CPU, the N8N frontend seems to disconnect, and workflow executions are not visible. I suspect the upgrade might have impacted resource handling or configuration settings, but I'm not sure how to resolve it.
The Docker startup command I'm using is as follows:
BASHsudo docker run -d --restart unless-stopped -it \ --name n8n \ -p 5678:5678 \ -e N8N_HOST="myn8n.my-domain.com" \ -e WEBHOOK_TUNNEL_URL="https://myn8n.my-domain.com/" \ -e WEBHOOK_URL="https://myn8n.my-domain.com/" \ -v ~/.n8n:/root/.n8n \ n8nio/n8n
Additional details:
- Version: 1.78.1
- Database: QLite (default: SQLite)
- n8n EXECUTIONS_PROCESS setting: own, main
- Running n8n via: self-hosted in Google Cloud
- Operating system: Windows10
I'm looking for guidance on troubleshooting why the frontend disconnect occurs and how to restore the display of workflow executions. Any insights or suggestions would be appreciated.

Below is a few points to double‑check based on our documentation:
-
Volume Mount Location:
The official Docker instructions persist n8n’s data in the /home/node/.n8n folder. In your command you’re mounting to /root/.n8n. In some cases the expected path mismatch can lead to issues (for example, missing encryption keys or other user data). Consider updating your volume flag to:BASH-v ~/.n8n:/home/node/.n8n -
Environment Variables & Reverse Proxy Settings:
Make sure that the environment variables such as N8N_HOST, WEBHOOK_URL, and WEBHOOK_TUNNEL_URL match your domain settings. When n8n is exposed publicly (or behind a reverse proxy) any mismatch can cause issues with the connections used by the frontend. -
Logs for Diagnostics:
Upgrading the VM’s CPU could have affected resource handling or timing. To investigate further, it helps to increase the log verbosity. You can do this by adding an environment variable like:BASH-e N8N_LOG_LEVEL=debugThis may provide clues in the container logs regarding the disconnect.
-
Network Settings & Firewall Rules:
Since your instance runs on Google Cloud, verify that there are no changes in the network/firewall settings after the upgrade that might be interrupting long-lived websocket connections which the frontend relies on.
By ensuring the data is persisted at the recommended path (/home/node/.n8n) and the environment is set up as outlined in the Docker installation documentation, you should be able to narrow down whether the disconnect is due to configuration changes or something introduced by the CPU upgrade.
Give these adjustments and checks a try, and if problems persist, reviewing the detailed debug logs will help pinpoint the root cause.
