Week 3 Programming Assignment: Unable to open the lab

I am getting the following message as I am trying to open the lab. Please help

Error

We were unable to retrieve a launch URL. Please make sure you are logged in to Coursera, and have access to this lab.

Hi, Abhishek.

Please close the browser and try login in again. Also, check the network speed and look whether windows is updated or not? If these don’t resolve the issue then seek Coursera’s student help corner. You might have logged in for a trial week that might have ended. You need to subscribe for a paid course to get started.

Here’s a brilliant thread that could be really helpful.
