Even though you've allowed outbound access for Synology, its possible that certain necessary services or ports (like for authentication or communication with Synologys cloud servers) are being inadvertently blocked.

Hi, have you tried to perform a precise traffic analysis on troubleshooting section of NGAF? Perhaps, on some traffic, the allow policy you create don't match properly.
