[BUG] Cloud TikTok scraper fails with ERR_PROXY_AUTH_UNSUPPORTED

Bug Description

I am using the paid SurfSense Cloud version with active credits.

The TikTok scraper repeatedly fails when scraping a common hashtag such as "Zara".

Error:

Page.goto: net::ERR_PROXY_AUTH_UNSUPPORTED at https://www.tiktok.com/robots.txt Call log:

• navigating to "https://www.tiktok.com/robots.txt", waiting until "load"

I also noticed:

• Reddit scraper returns Success but 0 items for "Zara"
• Google Search scraper returns Success but 0 SERP pages for "Zara"

These results also happen directly from the SurfSense API Playground.

Deployment Type

• SurfSense Cloud (hosted version)
• Self-hosted version

Steps to Reproduce

1. Open API Playground.
2. Select TikTok scraper.
3. Use hashtag "Zara".
4. Run the scraper.
5. The request fails with ERR_PROXY_AUTH_UNSUPPORTED.

TikTok input:

{ "hashtags": ["Zara"], "max_items": 10, "results_per_page": 10 }

Reddit input:

{ "search_queries": ["Zara"] }

Google Search input:

{ "queries": ["Zara"] }

Expected Behavior

TikTok should return scraping results instead of a proxy authentication error.

Reddit and Google Search should return results for a common query such as "Zara".

Additional Information

This happens directly in the SurfSense API Playground, not only through my application.
