Impossible to connect to Adobe server for using Photoshop 2021

Hi. For at least 1 hour, my Photoshop is not able to connect to the Adobe server for reading my licence and I am stuck. I am using the latest version of Photoshop 2021 and the latest version of Adobe Creative Cloud. I tried a lot of stuff to fix it, but nothing work: my WMI service is running well, there is no issue with the Credential Manager from my Service Manager (I think), everything is updated, and more checks. I don't understand what is going on. I was using Photoshop 2021 normally and suddenly the software stop responding at all randomly and when I restart it, the problem appears. I am on Windows 10 64-bit, core i7-3770, NVIDIA GeForce GTX 1050 Ti. Any help will be appreciated.
