Tls Error: Tls Object -> Incoming Plaintext Read Error
the most common problems in setting up OpenVPN is that the two OpenVPN daemons on either side of the connection are unable to establish a TCP or UDP connection with each other. This is almost a result of: A perimeter firewall on the server's network is filtering out incoming OpenVPN packets (by default OpenVPN uses UDP or TCP port number 1194). A software firewall running on the OpenVPN server machine itself is filtering incoming connections on port 1194. Be aware that many OSes will block incoming connections by default, unless configured otherwise. A NAT gateway on the server's network does not have a port forward rule for TCP/UDP 1194 to the internal address of the OpenVPN server machine. The OpenVPN client config does not have the correct server address in its config file. The remote directive in the client config file must point to either the server itself or the public IP address of the server network's gateway. Another possible cause is that the windows firewall is blocking acc

When I test the setup on one of my Linux virtual machine clients, I get the error: TLS Error: TLS handshake failed. I quickly read (OpenVPN on OpenVZ TLS Error: TLS handshake failed (google suggested solutions not helping)) and tried to switch from the default UDP to TCP, but that only caused the client to repeatedly report that the connection timed out. I also tried disabling the cipher and TLS authentication, but that caused the server to fail with Assertion failed at crypto_openssl.c:523. In both instances, the required changes were made to both the client and server configurations. I have been following the instructions at (https://wiki.archlinux.org/index.php/OpenVPN) to set up OpenVPN and the instructions at (https://wiki.archlinux.org/index.php/Create_a_Public_Key_Infrastructure_Using_the_easy-rsa_Scripts) to create the keys and certificates. The only deviations I have made from these instructions have been specifying my own computers' names and their corresponding key/certificate file names. See also my original question about securing SMB traffic over the Internet: (Simple encryption for Samba shares) Can anybody explain how I can solve this issue? Details: Server: A

Last year, we followed that video an were successful without connections, without doing anything special. Our users are authenticating using RADIUS (which works since have captive portal working also), and we are using port 1194. Logged kejianshi Hero Member Posts: 4546 Karma: +179/-25 Debugging... Re: OpenVPN Errors - TLS handshake failed « Reply #1 on: September 03, 2014, 01:58:23 pm » Well - Yes - You have to open the port that the vpn server communicates on. Thats a simple firewall rule on the WAN to pass traffic, either udp or tcp depending on what you are using. Not a NAT rule.If you used the wizard, a port should have been opened on the WAN for you.Got to firewall, rules, WAN and check to see if its there.Also, clock sync can be an issue if the client is ahead of time/date compared to the server.Good to provide a good NTP server list.
