Update: Seems like Jolla added IPSec support via the VPNC package, so you are correct that it should work. For a long time, SFOS only supported OpenVPN, hence my assumptions on the original post. Sorry to miss the update.
So, what are the errors you are getting when the connection fails?
Original post (outdated):
Based on your title and a quick research, I'm pretty sure that the FritzBox VPN bases on IPSec, while the VPN implementation in SFOS is based on OpenVPN. These two protocols are completely different and not inter-operable, so your only possible options are:
- get IPSec support on your Jolla (most likely with strongswan): As far as I know, there is no easy way for that (no App or GUI), you'd have to compile the package itself and manage everything from the command line
- switch the VPN on FritzBox to OpenVPN: This seems not possible, since FritzBox does not have OpenVPN support in its Firmware (and most likely will not add it).
So unless you have some knowledge in compiling and shell management and are willing to experiment with it, there's no way in connection your Jolla to a FritzBox. Nevertheless, feel free to contact the Jolla Support (https://jolla.zendesk.com/hc/en-us/requests/new) to confirm my assumptions (and show them, that there is a demand for IPSec support).
One thing you could do of course is running an OpenVPN server behind your FritzBox, if that is an option for you.
