what means RROR User auth failed “Duplicate nonce”
i cant find description of error anywhere.
I have this error and people cant turn on vpn
As an added layer of protection the OpenVPN password field in the Pritunl Client is encrypted with NaCl and a nonce is included. This prevents the password from being read and prevents it from being used more than once. Sometimes the OpenVPN will reattempt connections when trying multiple hosts and it can be inadvertently processed twice. Network load balancers can also cause the issue to occur. When the error occurs it usually indicates there are issues with the configuration or connection.

only password? i use pin.
Could you please explain or give me example:
Sometimes the OpenVPN will reattempt connections when trying multiple hosts and it can be inadvertently processed twice.
I’m referring to the password field in the OpenVPN connection. That will include the pin and for most configurations cache or single sign-on related tokens. I don’t have specific examples on when it will occur. The configuration uses ping-exit to exit on connection failures which allows the Pritunl client to create a new connection with a new encrypted password. There are some connection issues where it will attempt the next host without an exit.
my logs have connect twice, so result has error of duplicate nonce. my pritunl client show me 2 error of: 1) timeout, then 2) auth. Second error i sure because duplicate, but why client try connect twice? do you have any guesses?
logs has also:
Inactivity timeout (–ping-restart), restarting
The timeout is likely a partial connection. It connected long enough to send the nonce to the server and the server expired it. If you modified the Ping Interval or Ping Timeout set it back to 10 and 60 seconds. Look at the logs and find the host that is causing the timeout and verify it is working.
