I’ve been working on extracting data from a medical website for a few days now and I’m completely stuck. The site seems to have really strong protection and I can’t get past it no matter what I try.
The Problem: I’m trying to get doctor information from a healthcare directory site using Python and browser automation tools. Every time I try to load the page, it either times out after waiting forever or gives me HTTP2 protocol errors. I’ve tried tons of different approaches but nothing works.
What happens when I try:
First attempt to visit any page just hangs for like a minute then fails
If I try to go to another page after that, it immediately crashes with network errors
Even using my real browser doesn’t work because it detects automation
Everything I’ve attempted:
Basic HTTP requests (expected failure)
Different browser automation libraries
Anti-detection tools and stealth plugins
Custom headers and user agent spoofing
Trying to use my actual Chrome profile
I’m starting to think they’re using some kind of TLS fingerprinting or enterprise-level bot protection service. The way it kills connections so quickly makes me suspect it’s happening at the SSL handshake level.
My question: Does this sound like TLS fingerprinting to you? Are there any Python solutions I haven’t considered, or do I need to look into premium proxy services at this point?
I’ve encountered similar enterprise protection on medical sites - you’re facing a robust system. The immediate connection termination after a failed attempt indicates that they’re closely monitoring your client fingerprint and responding quickly to anomalies.
Before spending on premium proxies, consider spoofing your TLS client hello using curl_cffi. This approach can replicate real browser TLS signatures, as standard request libraries often signal “bot” activity and are easily identified by these systems.
It’s also worth investigating canvas fingerprinting or WebGL detection, as many sites employ various fingerprinting techniques. In my experience, using selenium-stealth with specific Chrome flags to eliminate automation markers, along with incorporating random mouse movements and realistic scrolling, has proven effective. It’s crucial to deceive multiple layers of detection simultaneously.
Had the same problem with a healthcare site last year. What finally worked was fixing my request timing. Those immediate crashes after the first attempt? That’s definitely sophisticated fingerprinting.
Add realistic delays between requests and mix up your timing patterns. Enterprise protection systems love flagging consistent intervals. Try undetected-chromedriver with custom Chrome flags to disable the webdriver features they usually catch.
You’re probably right about TLS fingerprinting, but test with a VPN before spending money on premium proxies. Sometimes these systems just whitelist certain regions or ISP ranges.
Been dealing with this crap on enterprise sites for years. Your crashes scream advanced bot detection - probably Cloudflare or Akamai.
Those immediate crashes after first contact? That’s real-time behavioral analysis. They’re not just checking your requests, they’re watching how you move through the site.
I stopped fighting detection layer by layer and switched to workflow automation that handles this mess automatically. It rotates everything - IPs, browser fingerprints, timing patterns, even execution environments.
I set up flows that mimic real users perfectly. Random pauses, mouse movements, realistic scrolling. The system handles proxy rotation and anti-detection without me worrying about Chrome flags or TLS spoofing.
For medical sites, I’ve found mimicking actual doctor lookup patterns works way better than systematic scraping. The workflow simulates someone genuinely searching for healthcare providers.
Best part? When they update protection, I just adjust the workflow instead of rewriting bypass code.
Check out Latenode for this setup. Way more reliable than fighting these systems manually: https://latenode.com
totally agree, sounds like their protection is on point. switching residential proxies could help, maybe try a few diff ones to avoid detection. also, opening the site in incognito could reveal if it’s server-side blocking. good luck!
