Vagrant ssh permission denied

I have no idea why ssh is required to need to connect to VM and why permission denied

mongodb-m042:
mongodb-m042: Welcome to M042 Vagrant Box
mongodb-m042: + set +e
mongodb-m042: + echo '
mongodb-m042: Welcome to M042 Vagrant Box
mongodb-m042: '

D:\My Files\university-mongoDB\M042\m042-vagrant-env>vagrant ssh
vagrant@127.0.0.1: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

@Rakshith_79674 is there a sub folder called Shared in that directory? If there is then Vagrant is using that sub-folder to sync whatever files you drop in there so that it can be accessible from the Virtual Machine.

I have a shared directory but it is empty
while vagrant up i found some warning that i did not understand
