Sync Client user/password Access forbidden by server

Hello Everyone,

I’ve just installed a new clean NC 13.0.5 and want to sync with desktop client, but I’m stuck on user/password screen. The cred’s I use to login to web client don’t work in the sync client. When I try to create a pwd in Settings/Security for an sync client and use it with mu username instead of the web pwd it also don’t work.
