Outdated client please use 17w06a

Hi,
I just updated the server to 1.11.2.
I opened my launcher that upgraded me to 1.11.2 too.
And now, when I'm trying to connect to my world on my server, I'm getting the message "Outdated client! Please use 17w06a"
I tried downloading the latest client from the website but same end.
What should I do next?
Thanks
