Neocore browser error 12029

[cagigas]

Hello RoboTask Support Team,

I am using RoboTask 10.6.0.324 (x64) and the built-in NeoCore (Electron) browser for Web Automation.

My use case is to capture screenshots from www.optionstrat.com. Unfortunately, the NeoCore browser fails very often during startup with the following error:

Network error: REST request failed: Error sending data (12029)
Could not establish connection with the server

This happens even before any navigation, during Start Browser (electron).
When this occurs, no Browser object is created and retries often fail unless RoboTask is restarted.

I tested Edge and Chrome, and they start reliably. However:

In headless mode, they do not save credentials.

When started with a persistent profile using Run Program, credentials work correctly, but the browser instance is not available as Browser1, so it cannot be used with RoboTask’s Web Automation actions.

Could you please advise on one of the following points?

Is there a recommended way to make NeoCore startup more reliable and avoid REST error 12029?

Is it possible to force NeoCore to use a persistent profile or user data directory?

Are there plans to allow external browsers (Edge/Chrome) launched with profiles to be attached to Web Automation as Browser1?

Is headless mode expected to support session persistence in NeoCore?

Any guidance or best practice for this scenario would be greatly appreciated.

Thank you for your time and support.

Best regards,
Oscar
