R8000 OpenVPN TLS V1.1

Something to make contact with OpenVPN and MS about.

Hi Tech community,

 

Firstly apologies if this has been covered before, I did try to search and though numerous posts regarding OpenVPN exist I couldn't see one for this use case.

 

I have updated a Windows based client to the latest OpenVPN release (2.6.7) and I am unable to connect due to TLS version mismatch, error message found in logs below:

TLS error: Unsupported protocol. This typically indicates that client and server have no common TLS version enabled. This can be caused by mismatched tls-version-min and tls-version-max options on client and server. If your OpenVPN client is between v2.3.6 and v2.3.2 try adding tls-version-min 1.0 to the client configuration to use TLS 1.0+ instead of TLS 1.0 only

 

OpenSSL: error:0A000102:SSL routines::unsupported protocol:

I have checked my router is running the latest firmware... am I to assume there is no current support for TLS 1.1 on R8000? So I will fall back to a earlier version of OpenVPN client for now but this is not ideal for security

 

Thanks in advance 

 

Luke

How long has it been since you re-created the configuration files and updated your client devices?

So far, I am not having any issues with the OpenVPN version 2.6.7 and the client configuration files created with my R9000.  The update to OpenVPN version 2.6.7 was a non event on Windows 10 client machines.  I did not update the client configuration files to use with the updated version 2.6.7 application.
