[SC] An existing connection was forcibly closed by the remote host

[farrel219]

Hi all.

Just started for me this morning, the error messages are generated by StreaMonitor when recording from Stripchat. Otherwise, the program record normally from Chaturbate. Anyone who can help correct this issue?

Thanks.

Look like they have implemented some mechanism to block non-browser clients, it's interesting... I'm wondering which information allows them to do that.

The status request still works. That's network related. I think two things are possible:

1. Blocked by the site based on IP which leads to a unconvinient blocking by doing TLS wrong.
2. Something intercepts TLS connections.

Can I use VPN to solve this problem?

The spawning of ffmpeg isn't the problematic part.

The status request fails.

Another possible issue could be the SSL/TLS Stack. stripchat.com has a really small and "hard" cipher suite active. So everything under TLS 1.2 isn't allowed the heavily use EC stuff and so on.

This could lead to problems with older Python versions. While Python on Linux/BSD/macOS is build with OpenSSL it should be no problem. I'm not sure whether Python is build with Windows Crypto Stuff on Windows. So the OpenSSL version or Windows could be also a problem in certain cases.

Line 992 of _ssl.c indicates that the Handshake fails (just based on a short look).

So make sure to have at least 3.11.x Python (3.12 seems to not work with StreaMonitor) and check your Crypto Stuff and with which Python is build.

At first, I also thought it could be that SC has disabled TLS 1.0 and 1.1 support, causing the issue. However, when forcing the request to use TLSv1.3, the issue still persists. I tried making requests on various systems, including MacOS and Unix, across different AWS Lightsail regions (such as us-west, asia-southeast, etc.), and the result remains consistent. It seems that the connection reaches Cloudflare, but it's being refused.

1. The exception the Python requests module thorws is related to TLS.
2. They have TLS1.2 and TLS1.3 activated with a thin cipher suite. Aspecially the handshake algorithms are EC stuff.
3. You get a working TLS connection. The reason you get a 406 HTTP Error is simply related to the fact that the server wants to see a Accept header. Just send a valid Accept Header like a browser would do and you can curl the mainpage. If your IP isn't blocked (DC, Hoster and some other IP-ranges can be generally blocked via CF).

Reference in new i

make a fork and if you believe you can fix this issue, i have been trying to fix it for a week.
