Is the proxy yours? Is it a SOCK5 proxy? To debug this, we will need the proxy's logs.

lookandhate commented 1 year ago

It's not my proxy, I purchased it. And yes, it's socks5 proxy

amaury1093 commented 1 year ago

Unless you have access to the proxy's logs, there's unfortunately not much I can do here.

lookandhate commented 1 year ago

Okey, I'll try to get proxy logs. Do not, please, close issue yet

lookandhate commented 1 year ago

So, sadly we can't access proxy logs and moreover, we can't check are 25, 487 and so on ports open or not. Thus, there is probably proxy problem.

Nyceane commented 1 year ago

Hey @lookandhate I am running into same problem, this time with port 25 open. I've tried commercial proxy and found out keep receiving that error so I setup my own dante server on ec2 (with port 25 open), but every time reacher hits it I keep getting that eror. If I use username/password via dante then I get a

"error": { "type": "SocksError", "message": "Auth method unacceptable[255]." }

Proxy server runs as following. dante refuse to log somehow and I am trying to figure that out.
