Connectivity error every time! PLZ Help!

First of all, Thank you for your valuable time. I was given a task to install and create bare git repo(my first task :slightly_smiling_face: ). I completed the task within minutes but when I clicked on finished button, it shows connectivity or session may have expired issue. I gave this several attempts, after reloading the page.Every time this error is occurring. On side note my connection is up and running efficiently but still I am unable to get rid of this issue. Please help, your early reply would be highly appreciated.
