Cannot Decrypt Channels on Octagon SF8008

I have two devices Octagon SF8008 and Formuler F1. I use the same oscam configuration on both, but while on Formuler F1 I can watch crypted channels, on Octagon I cannot. I've tried different enigma2 distros; OpenATV, Hyperion, DefineOS, etc., but the issue persists on all.
When I start oscam (on Octagon) I receive about 20+ online proxies but in a very short time it becomes "Proxies X/X (0 of X online)"
What are some things I should do to debug this problem?

Thank you for the prompt reply.
From what I can see on the logs there is clearly a communication between oscam and the servers, and yet no descrambling on the screen.
And I should mention that I use free test servers

I don’t mean to waste anyone’s time, but I’m curious about why these servers work on the Formuler F1 but not on the Octagon SF8008. This issue isn’t limited to OSCam; it also occurs with CCCam.
If this is against the rules, you may close or delete the thread.
Thank you

Update: Everything is working now.
Speculation: I have been using a rather aggressive line tester, so it is possible there was a IP/MAC address blocker. Since then I've reduced the testing to one active line per server address 🤔
