Cannot synchronize Joplin app

Operating system

Android

Joplin version

3.1.8

Sync target

Joplin Cloud

What issue do you have?

Hi Joplin team,
I tried to synchronize my Joplin app with my account. But there is a « Your Joplin Cloud credentials are invalid, please login ». I think it's OK. There is a link « Authorize » that leads me to the web page of my account on which I log in with success. Then, I go back to the app and I have a « Erreur:Network request failed ».
Anyone has ever faced this error?
Thanks,
asan :fox_face:
