SSL VPN Remote not adding all routes

Hi all,

I have multiple s2s connections that all work fine.

I've setup a SSL VPN server for remote access and configured firewall incl nat rule so clients can tunnel through all sites.

I also have a s2s to azure but the tunnel doesnt seem to work from remote clients.

the network is in permitted network resources (restarted the vpn service) but the route is not added.

I also read something about /16 networks that can cause conflicts so i already changed it to /24.

When i manually add the route (windows client) i can reach the network in azure.

I've restarted the VPN services and downloaded the configuration file afterwards but the remote network of azure is not pulled.

Logging of the client:

It looks like the last route that needs to be added fails.

Do i need to reboot the firewall for this?

subnets are all different from eachother so no collisions there.

Does anyone have a idea to push me in the right direction?

Thanks in advance!
