PydioSync failed to connect / no log


here are my configuration details:
PydioSync : v2.2.0
OS : Win 10

I just install PydioSync on a new fresh laptop and the client fails to connect: error message is to check server url but i’m using the same as on my other laptop which works great and also on the web.

Is there any other log files with more infos ?

Thanks for helping.
