Authentication Required (407)

I am having the same issue. For me is working inside browser but the desktop app is giving me this message.
Only Info I found so far ( but for us it can’t be done)

• Ask your IT department or systems administrator to unblock Port 443. This is the standard port for websites that are run over SSL (Secure Sockets Layer - https).

Anyone else has found a solution for this ?
thanks

Hello, has someone found a solution ? I’m having the same problem.

@sonia11 The guidance for this has not changed, and is still similar to what was included in the original topic details.

If you’re using the Desktop App behind a Firewall, proxy or Virtual Private Network (VPN), you may see the error message: Connection Error (407).

You have two options:

• Use Figma in the browser. You can access the Figma web app from any of our supported browsers. Learn more in our What Platforms, Devices and Browsers are Supported? article.
• Ask your IT department or systems administrator to unblock Port 443. This is the standard port for websites that are run over SSL (Secure Sockets Layer - https).

If you still have trouble after running through the above, we may need you to run some diagnostics + connect you to our support team.
