Post by dongchul » Thu Oct 19, 2017 9:14 am

Hi,

I get error 'Cannot open TUN : Permission denied (errno=13)'
My device android 6.0, rooted, also used same config file(*.ovpn)
I build on openvpn opensource apk. run 'ok'
build another my application. run 'error'
my application near similar same with opensource openvpn.
(Importfile -> start vpn service -> start process thread)
but my application got error :(
what's the matter? Do you have solution?

The VPN which you are using may have been expired so you are facing this issue so you have to update it and if you have the subscription and you are facing this issue then you should contact Microsoft Office Support for the help
