pfsense 2.7 impossible to upgrade to pfsense plus

[mathais]

hi,
Impossible for me to upload from 2.7 to pfsense plus.
I added the token, but now, I have the message : "Unable to check for Update"

I looked the troubleshooting documentation, but that d'ont help me...

I have no proxy on my network.

Thank you,

I tried :

kg-static clean -ay; pkg-static install -fy pkg pfSense-repo pfSense-upgrade

But result is not good :
