Problem during the checkout process : can't see payement step

I just switch to the pre-release Commerce 1.1.0-rc1 but it’s look the issue was there just before, and I don’t know what’s appends precisely.

As I’m running 1.1.0-rc1 now, I have set the WebHook for the Stripe gateway and it looks good on Stripe Dashboard WebHook : there were well created by Commerce as said on doc.

During the checkout process, after selecting the shipping address, I couldn’t access to the payment step (Stripe) anymore and I have this error on the browser appears after a while (15s seconds) : “The page couldn’t be redirected correctly”
On server log I have no errror, just this on the access log :

I don’t know how to debug further…
