Attention

xxx.ovpn configuration file

If you don’t use ovpnString, don’t forget to add the configuration file to your project

  • The Android path is android/app/src/main/assets/，create a new assets folder if you don't have one

  • The iOS path is the main bundle, just drag and drop the file into the project

    ios-ovpn-file

The format of the line where remote is located in the file must be of the following form

...
remote <IP address> <port>
...

If you don't need to dynamically modify the remote address in the configuration file, the same configuration file is used for Android and iOS, and the remoteAddress of options can be left out

However, if you need to dynamically change the remote address in the configuration file, the iOS configuration file needs to comment out the line where remote is located (below) and always pass remoteAddress for options

...
;remote <IP address> <port>>
...
