Login Failure (Minecraft Launcher) with Qustodio

A little while ago I started experiencing a problem with my Minecraft launcher. I could only 'Play Offline', and when I tried to connect to a server I got an invalid session. Somewhere (I forgot where, sorry) some guy said to logout and log back in. I did this, and now I can't log back in. I get this message:

Sorry, but we couldn't connect to our servers.

Please make sure that you are online and that Minecraft is not blocked.

*(EOF Exception: SSL Peer shut down incorrectly)*

The launcher log from before I logged out is at http://paste.ubuntu.com/16580291/.

My son has qustodio and was having this same issue with Minecraft. I e-mailed qustodio customer service and was given a very quick response with a procedure that solved the problem! My son is now back to using Minecraft. I hope it works for you, here is the text from the e-mail:

Hi, We have resolved the issue and reinstalling should address it. So, can you please try again to install on your computer by following these exact steps?

• Uninstall any security suite from your computer
• Restart your computer
• Log into the computer with an admin account
• Make sure you are connected to the internet
• Download a fresh version of Qustodio from here: http://www.qustodio.com/family/download
• Follow the installation steps provided.

Then, please make sure to install the very last updates of Windows and of your web browser and restart your computer. If everything works fine then, you should be able to reinstall the antivirus safely.

Same thing happened on my kids computer. Games other than minecraft, like Battlefield 4 and PVZ are also affected. Once I noticed the SSL error, and realizing that qustodio intercepts SSL traffic to perform a MITM "attack", I uninstalled qustodio. With qustodio gone, everything works again. Sadly I just paid for another year of qustodio, and I don't know why they broke it recently, but that was the issue.
