<b>If you are a Tango Pro or Enterprise user experiencing technical difficulties such as:</b>

Workflow images display as a blank or “Image failed to load” error

- Unable to initialize Tango Desktop App
- Desktop App stuck in an initiation state
- Workflow images display as a blank or “Image failed to load” error
- Updates never arrive

Allow the domains below in your firewall or proxy. Tango Desktop uses HTTPS only.

Allow the wildcard entries as written so that services we add behind a new subdomain don't get blocked. If your network decrypts SSL traffic and you're still having issues, exclude these domains from decryption.

- <code>*.tango.us</code>
- <code>*.amazonaws.com</code>
- <code>edge-config.vercel.com</code>

This list is current for Tango Desktop 2.0 (September 2026). Desktop updates are downloaded from <code>desktop-downloads.tango.us</code>, which is covered by <code>*.tango.us</code>.

If you're capturing a Workflow on a protected network, a firewall or proxy can block the Tango Desktop app. Here are the domains to allow.

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.
