Proxy keeps asking for authentication all the time

[Antonn1]

Hello,

I successfully setup mitmproxy and it's dependencies and when I run the proxy with a password, it just keeps asking for the password. Even though the password entered is correct.

This only started happening after I reinstalled the server and installed mitmproxy again.

Am I missing something?

I'm not quite sure what your issue is based on what you are writing. Could you please describe your issue using the template at https://github.com/mitmproxy/mitmproxy/blob/master/CONTRIBUTING.md?

Hello,

Apologies.

Basically, what I'm trying to say is that the device which connects to the proxy is always prompted for authentication details even if the authentication provided is correct.

On a previous installation (~2 months ago) it worked fine on Ubuntu 14.10. Now after formatting the server to 14.10 again and reinstalling mitmproxy and it's dependencies, it installs like before but when I start the proxy and connect my device to it, it just keeps asking for authentication details no matter what I insert in the user & pass box.

If I run the proxy without authentication it works as it should but with authentication, it's giving me issues. So I was thinking maybe I'm missing something?

Thanksfor the clarification.

1. How do you start mitmproxy (which parameters?)?
2. Which client do you use? How did you configure it to use the proxy?

I use screen to keep it running in the background so:

screen mitmproxy --singleuser user:password -s file.py

I haven't done any configurations. Just installed and started the proxy. :)

Which client do you use? Firefox? Chrome? Your-Random-App?
If it's a browser: Does this happen for all websites or only for HTTP, only for HTTPS, ...?

[Antonn1]

I use an iOS & Android device. And it happens for all websites apparently.

Any ideas?

On a previous fresh install, it never used to ask for the authentication password all the time. I will format the server and retry again.

Nothing yet.

Can I install an older version of mitmproxy? Maybe an updated version is causing the issue for me. Because on the old server, I never updated packages.

I just commited a fix that affected HTTPS connections only. You can install mitmproxy from master using

pip install git+https://github.com/mitmproxy/netlib.git@master
pip install git+https://github.com/mitmproxy/mitmproxy.git@master

You mentioned HTTP connections are affected as well - does this fix your issue though?

[Antonn1]

I'm not sure how to install it that way. Got an error.

Sorry.

Sorry about that. I think we have plenty of installation instructions out there.
