There are currently three fixes for the DNS issue on iOS.
Add the DNS server to the server routes. The default DNS server used is
188.8.131.52 add the route
184.108.40.206/32 to the server routes for this configuration.
Remove the DNS server from the settings. This will instruct the client to use their current DNS configuration. This could cause problems with some clients if that DNS configuration becomes unroutable due to the VPN routes.
Enable VPN Client DNS Mapping in the advanced server settings. This will start a DNS server on the Pritunl server that will proxy all DNS requests and will always be available to the client.
