Decodo Proxies Not Working with n8n-nodes-puppeteer

[marekf93]

Description of a problem

When I try to use Decodo proxies with n8n-nodes-puppeteer, all proxy configurations fail with a 401 error code. This occurs regardless of which proxy setup is used (user, HTTP, HTTPS, or SOCKS5).

Environment
Tool: n8n-nodes-puppeteer
Proxy Service: Decodo
Error: Request failed with status code 401

Steps to Reproduce

1. Configure n8n-nodes-puppeteer with Decodo proxy credentials
2. Set up operation (Get Page Content)
3. Try different proxy configurations:

HTTP
HTTPS
SOCKS5
With user authentication

4. Attempt to access a page that is definitely accessible

Current Behavior
All requests fail with a 401 error regardless of proxy configuration type.

I am attaching screenshots showing:

The n8n-nodes-puppeteer configuration interface with the proxy settings + the 401 error response received
The Decodo proxy management dashboard showing valid proxies

Is there a known compatibility issue between n8n-nodes-puppeteer and Decodo proxies or any special configuration requirements for Decodo proxies that aren't covered in the documentation? Could there be an authentication formatting issue when passing credentials to Puppeteer?

Thank you for any help..
