Problem to obtain Token

Good morning,

I’m trying to link google photos with “photonic” in my wordpress webpage.

The thing is that I’ve been able to verify my google account but I haven’t been able to get the “token”. Once I click on “get token” link. the page won’t stop loading.

Could it be related to the fact that I have a gsuit account?

How can I solve the problem?

Thank you so much for your attention.
