Since version 2.40 request over the internet over an proxy requiring authentication, doesn't work anymore. The proxy-server doesn't get authentication credentials from mp3tag.
Proxy-Auth is broken since version 2.40/2.40b.

Can you send me a URL and a temporary login for reproducing the issue?

Unfortunatly i don't operate any public accessible proxy-servers, but if you like, the squid proxy-server is avalaible for windows under:
[http://www.acmeconsulting.it/SquidNT.html](http://www.acmeconsulting.it/SquidNT.html)
Direct DL-Link:
[http://squid.acmeconsulting.it/download/sq...TABLE18-bin.zip](http://squid.acmeconsulting.it/download/squid-2.6.STABLE18-bin.zip)
unpack it to drive c:\ (should unpack an folder squid)
rename all files under C:\Squid\etc\*.conf.default to C:\Squid\etc\*.conf
replace content of squid.conf with the following
file c:\squid\etc\squid.conf:
#authentication (basic)
auth\_param basic program c:/squid/libexec/ncsa\_auth.exe c:/squid/etc/passwd.txt

create a file name passwd.txt in the C:\squid\etc\ folder with the following contents:
file passwd.txt:
user:VT8RFQ8zt7op2
\<\<
this will create a user named 'user' with an password of 'pass'
open a cmd-windows, then cd to C:\squid and type sbin\squid -z and after that type
sbin\squid -D
leave the window open , your proxy is now running on 127.0.0.1 port 3128
try tu use the proxy within mp3tag
any access/errors are logged to c:\squid\var\logs\access.log

I've tried with Squid and Basic authentication (had to adjust the password using htpasswd) and everything works as expected using the current [Development Build](http://developer.mp3tag.de).
Are you sure that your proxy requires Basic auth? If so, you can also try to increase the timeout value.

Sure, if I set it to not require any authentication (excluding some urls requiring authentication),
it works perfectly. Please note that for me theres is no direct access to the internet/dns-servers, thus all traffic designated to the internet must go through a proxy.
I've installed Version 2.40c: at least now the base64 auth-credentials seems to be submitted, but i don't get an final response from proxy (forcing basic-auth: request from mp3tag get an TCP\_DENIED/407 anyway) . I'll try to do a dump, to see what is different between version 2.39 and 2.40c concerning proxy-handling. Hope to find an explanation through, why it ceased to work since 2.40.

Any news on this? Anyone experiencing the same problems?

I have the same problems (with v2.42, v2.42f and v2.42h)
I am sitting behind a proxy that needs username (domainname\username) and password. The error message is:
"The server failed to return a valid query response code"
How can I help you to find the problem?

Does your proxy require digest or basic authorization? Only the latter is supported by Mp3tag.

As far as I know my proxy doesn't use basic authorization (not coded) but "ntlm v2" (coded).
So no chance for support ?

Unfortunately, I don't plan to support other authentication schemes than basic.
