another OpenVPN issue
Guess it's from a recent app update on both Android and W11. The connection attempt fails every time. The only warnings/errors I see are: Fri Jan 9 16:10:22 2026 WARNING: No server certificate v...
There was a discussion recently about the server certificate verification method warning. This is similar to the warnings that modern web browsers issue when connecting to the Netgear router management web site
- http site: WARNING. insecure. (site is not encrypted)
- https site. WANRING. insecure (self-signed certificate)
The solution in both of those cases is to ignore the warning and tell the web browser to proceed to the site (while grumbling aloud, "this is MY damn router on MY network. quit bugging me.")
The TLS error is the problem.
The default configuration file for Windows is a tap connection. My practice is to modify the configuration file and change the connection type to tun (tunnel) on port 12973 (rather than 12974 - tap)
OpenVPN does not support tap connections on non-Windows and smartphones.
Huh. My existing profile is for TUN on port 12973. I was trying to use the smartphone .ovpn on W11 which worked fine in the past on W10.

Did you remember to rename the VPN adapter name to NETGEAR-VPN ?
Also, does this also fail on your phone?
I've never manually renamed the VPN adapter. Right now on W11 (which should be the same or essentially so on W10 which has worked) it's named OpenVPN TAP-Windows 6. Additionally, the Pixel 9 which again was working fails in the same manner.
