So you’ve upgraded your datagrip or tools license and now want to use all the new fancy changes in the latest version of your database manager; and then you find out that you can no longer connect to your vagrant server? Well I have a solution for you.
Check your ~/.ssh/known_hosts (or c:/Users/USERNAME/.ssh/known_hosts) file on your development pc (not your VM) and you should find any entries regarding 127.0.0.1:2222 or []::2222 which are the default hosts for vagrant.
Remove those then try reconnecting and you should be good to go.
Hope that helps!
