Error when connecting OAuth Portainer

[jerome6994]

Good morning
Great job I love your product.
Despite my beginner level, thanks to the documentation and videos (of copptonian) I was able to embark on the authentik adventure.
I'm at the OAuth part on portainer.

I have a problem at this level.
I don't think it's a bug but more a problem coming from me, from my config

I have the OAuth button which is present on the connection page. when I click on it the process starts until I get the message: Invalid OAuth state, try again.

Without doing anything, I click a second time and the connection is made without error without any message!
Do you have any idea of ​​the possible cause? I watched the videos again and I don't see what I could have done to get it!

Thank you for you precious help
