Server TLS version is too low.
Hi,
I have been using OpenVPN on my TP Link Archer for years without any issues. Recently OpenVPN client on my iPhone was updated to 3.4.0 (5457) and it has stopped working with the message 'Authentication Failed. Server TLS version is too low'. I can still connect with previous version of OpenVPN client from my Windows desktop. Unfortunately I can't downgrade the OpenVPN client on my iPhone. Any workaround or firmware update happening? Please help!
Thank you.

I'm facing the same issue as @humgurung but on a TP Link Archer VR900 v2. There is no new firmware available yet. Do you plan to publish a new one?

Same error since a week ago. Not able to fix it.
I can go to advanced settings and enable risky protocols, but the actual services that I use openVPN for (cctv) don't work anyway.
Needs firmware update.

@Sunshine There is a setting in my android open VPN client (under advanced) which allows insecure connections. Since I use VPN to access home from the mobile netwoek, not to protect transactions from insecure WiFi venues, I can live with this risk.
So I ticked the box, and voila, no more 'out of date cersion' error. Just FYI. I am not recommending it.
