Known issue on the current image (as of 2026-09-15)

flowise.service crash-loops on the current image (Node.js CommonJS loader error), so http://<VM-IP>:3000/ never answers even though /var/lib/flowise/admin-password is written. (image build tested: 2026.628.1945)

What you will see: `systemctl status flowise` shows a restart loop; `sudo journalctl -u flowise` shows a `node:internal/modules/cjs/loader` error; first boot reports "Flowise never responded after 10 attempts".

Fix status: Fix in progress: azure-packer-image-factory PR #221 (proven on a rebuilt image 2026-09-16; ships with the next published version) — a fresh build of the current Flowise release whose first boot waits long enough for Flowise's slow first start (about 6.5 minutes on a 4-vCPU VM) and verifies the sign-in the way the Flowise UI does. The image is also 79 days stale. No proven workaround on the current image. Track the fix.

Source: our 2026-09-15 image sweep of the newest published build. This notice is removed when a build that passes the same test is live on the Marketplace.

Quick start

  1. Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
  2. Allow inbound SSH (22) for yourself plus the application port(s): 3000 (web UI) — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
  3. Open http://<VM-IP>:3000/ and sign in as dcaadmin (see First login below).
  4. Add your model provider credentials (Credentials) and build your first chatflow; put TLS in front before real use.

First login / credentials

This image generates its admin credential on the VM at first boot — nothing is pre-set. SSH into the VM with the username + key you chose at deploy, then print the generated credential:

ssh <your-username>@<VM-IP>
sudo cat /var/lib/flowise/admin-password

Sign in as dcaadmin.

  1. Print the credential file: FLOWISE_USERNAME=dcaadmin and FLOWISE_PASSWORD.
  2. Open http://<VM-IP>:3000/ and sign in with those values.
  3. To change the password edit FLOWISE_PASSWORD in /etc/default/flowise and `sudo systemctl restart flowise`; delete the file once stored securely.

Sign in as admin (unless noted), then change the password immediately. The file is root-only and can be deleted once the password is stored securely.

Still stuck?
