authorization failed for all operations on web kukai.app - GG login

[fabiello]

Hi everyone, I'm using kukai with GG authentication, I like it but I'm having often problems.
Sometimes I received authorization failure for all operations, but after rebooting the router (dynamic ip internet provider) it used to work again.
Actually today I tried many times with no success, I logged out and cannot log in back.
Any help will be appreciated
