Problem with OpenVPN and Proxy auth

[tcw]

Hello, im trying to using openvpn + squid proxy with auth but when I try to log in I get:
EVENT: PROXY_ERROR info "myserveripandport" : HTTP proxy Basic authentication not allowed by user preference

My squid proxy has this config regarding the authentication:


auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated



Using the windows openvpn application I can connect with no problem using these:

http-proxy xx.xx.xx.xx 3128 stdin basic
<http-proxy-user-pass>
user
pass
</http-proxy-user-pass>

PC LOG:
Thu Aug 23 16:58:03 2018 Attempting Basic Proxy-Authorization
Thu Aug 23 16:58:03 2018 HTTP proxy returned: 'HTTP/1.1 200 Connection established'
...
...
...

But it seems that the android version doesnt support the part of the config im using for the PC version.
So I have manually added it to the proxy list in the android app and checked the box use basic authentication.
I dont really know what is the user preference the error is referring to.



Hope someone can help me, thanks.
