ja3 tokens above not working - tls: error decoding message.

But the next token works, but its for Chrome:

it's weird to get 771, it can't be chrome, 771 is tls 1.2, chrome is tls 1.3 (772). most of online ja3 fp are out of date, you should check https://scrapfly.io/web-scraping-tools/ja3-fingerprint which seems to be the most accurate

i found a fix for myself

make sure you dont have 41 in your SSLExtension part of the ja3. 41 = pre_shared_key cycletls cant use this when it doesnt know/have the shared key already i don't know whether its ja3 will update to show it does after its got a shared_key

772 is never a valid number for TLS
