OpenVPN Connect: "Required credentials are missing" and "NEED_CREDS [FATAL-ERR]"

Description

If you're using OpenVPN Connect 3.5.0 or newer, you may encounter the following error when attempting to reconnect the VPN connection after your device wakes up from sleep or is unlocked:

Required credentials are missing for the reconnection attempt

and/or 

EVENT: NEED_CREDS [FATAL-ERR]

The error occurs when your .ovpn connection profile contains the auth-nocache directive and no session tokens are being utilized for the server-client connection. In this scenario, any time the device attempts to reconnect, it sends the cached credentials to the server. The auth-nocache directive prevents using these cached credentials, resulting in the errors mentioned above.  Earlier versions of the Connect App don't support the auth-nocache option. 

Solutions

1. Contact your administrator: Contact your VPN server administrator and request new connection profiles that don't include the auth-nocache option. We recommend implementing session tokens to enhance connection reliability.
   
   
2. Modify the .ovpn profile manually: If you can't contact your administrator, you can manually modify your .ovpn profile. Follow these steps:
   1. Locate the .ovpn file associated with your VPN connection and open it using a text editor of your choice.
   2. Find the line that contains auth-nocache and delete it.
   3. Save the modified .ovpn file.
   4. Import the modified profile back into OpenVPN Connect for use in your connections.
