Model: Archer VR1210v  
Hardware Version: V1
Firmware Version: Archer_VR1200v(SP)v1_1.0.0 0.8.0 v600e.0 Build 220626 Rel.52987n

Hello

 

Im having troubles connecting to my VR1200V HARDWARE VERSIONE V1 and using OpenVPN

I have setup a DYNDNS dynamic redirection and enabled OpenVPN server, then generated the certs and downloaded them.

 

Once I try to connect, it gives me the following error:

2023-05-21 10:28:44 TLS: Initial packet from [AF_INET]MY IP: MY PORT, sid=b37a9a24 a209f3ff
2023-05-21 10:28:44 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
2023-05-21 10:28:44 OpenSSL: error:0A000102:SSL routines::unsupported protocol
2023-05-21 10:28:44 TLS_ERROR: BIO read tls_read_plaintext error
2023-05-21 10:28:44 TLS Error: TLS object -> incoming plaintext read error
2023-05-21 10:28:44 TLS Error: TLS handshake failed

 

Then the process is restarted but it fails to connect.

 

Any solutions would be greatly apreciated.

 

Ps.

  1. The model correct is VR1200V V1, this model isn't present into model menù.
  2. I try add tls-version-min into client config.. it don't work.

Hi, when you change the minimum TLS version on the VPN client, did you change it to TLS 1.0?

Please share with us the screenshot as well.

 

Besides, may I have the version of your OpenVPN Client software? and you are using smartphone or computer to connect the OpenVPN?

Hi, thanks for the reply, may I know if you've tried any older version OpenVPN client such as 2.5.x? is it still the same error when connecting the OpenVPN?

 

In addition, please help to collect the following information:

1. Your ISP name, is it ADSL or VDSL line?

2. Please verify if the modem Internet IP address on Advanced->Status page is a public IP and the same as the one resolved by DDNS domain name

3. Screenshot of your OpenVPN Server settings

Hi, on the Windows computer, could you please try using OpenVPN Connect 3.3.4 to connect the OpenVPN Sever? 

Based on our tests, it works fine when using OpenVPN Connect 3.3.4.
