OpenVpn:TLS Error: TLS handshake failed

[yash]

Hello All
I had been tried to connect VPN from Pfsense , but it triggered to below error.

TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

That means the server received no response from the client. It could mean that the client is connecting to the wrong IP address, or that the traffic is being blocked before it reaches the server, or one of several other scenarios. Check the server log. If nothing shows up there at all at the same time the client tried to connect, then it's almost certainly a connectivity or firewall problem.

Hi jimp

Thanks, i have been seen that openvpn service is running in pfsense 2.4.4, i would like you to share the error read UDP: Unknown error (code=10054) believe that pf-sense is blocking incoming connection.

Sure, by default any connection incoming is blocked on WAN.
If you created your OpenVPN RAS with the wizard it will create some Firewall Rule for you.
If you created OpenVPN RAS manual you need to put your Rule at WAN manual.

Where exactly is this error? On the client? Or the server?

As mentioned by Rico the wizard will auto create the firewall rule, but it might be on the bottom and a rule above it might block? Post up your wan rules if you have questions on if firewall is blocking etc..

You need to validate that port is open from your client to the server.. It could be blocked at your client side, etc.. Or sure you could be blocking it on pfsense, or some nat router between.

Is that IP your public IP that you xxxxx out?

Lets see your firewall rules on your wan to validate 1199 is open.. Also your pfsense is not behind a nat right? And has public IP on its wan? Simple sniff on the wan for UDP traffic 1199 and then try to connect with your client will tell you for sure if the traffic is getting to pfsense or not.
