Ad-hoc n8n Workflow & Networking Support

I run a self-hosted n8n instance (Docker on Ubuntu) that integrates with Google Sheets, Pipedrive, Outlook, SharePoint/OneDrive, Ollama on WSL, and assorted APIs through the HTTP Request node. Occasionally I need help troubleshooting a workflow, and I need quick, expert eyes to trace the error, patch the node, or tweak the credentials. I'll also need help when LLM calls or AI agents (esp. using tools) behave erratically.

In addition, the rest of my team needs to log in, build, and test workflows. Right now the instance runs locally on my PC, inaccessible to anyone else. I’d like a secure, low-friction way (tailscale?) for colleagues to reach the UI without exposing the host to the public internet.

This will be for ongoing, ad-hoc support; expect sessions of an hour or so at at time whenever an issue appears. Thanks!
