All offered SOCKS5 authentication methods were rejected

[scythargon]

Hi! I've used this Docker image to setup a Socks5 proxy on my remote server https://hub.docker.com/r/serjs/go-socks5-proxy/ and it seem to be working:

$ curl  --socks5-hostname 195.201.21.5:1080 --proxy-user argon:rknshouldnotpass  http://ifcfg.co
195.201.21.5

But your library fails to connect:

In [1]: import socks
   ...: s = socks.socksocket()
   ...: s.set_proxy(socks.SOCKS5, '195.201.21.5', 1080, 'argon', 'rknshouldnotpass')
   ...: s.connect(("www.sourceforge.net", 80))
   ...:

Could you please tell me what am I missing here?

Thanks!

Have you solved this problem?

[scythargon]

@xucheng2008 nope, I believe I gave up on this

[runetech0]

The solution is simple. Just replace "s.set_proxy(socks.SOCKS5, '195.201.21.5', 1080, 'argon', 'rknshouldnotpass')" with "s.set_proxy(socks.SOCKS5, '195.201.21.5', 1080, username='argon', password='rknshouldnotpass')".. That worked for me.!

In my case, socks5 configure didn't have proper setting -- after permit all from intended origin, error has gone :)
