OpenVPN on Android stopped working with Orbi RBR20
OpenVPN on Android has been working fine with my Orbi RBR20 router for years. However, the Android app updated in May and now it no longer works. When I try to connect I get an error message: "OpenSSLContext: SSL_CTX_use_certificate failed: error:0A00018F:SSL routines:ee key too small". I sympathize that larger keys should be encouraged, but since I can't change the key size in the ovpn file generated by the Orbi, I seem to be dead in the water. Is there any way to fix this? I tried putting a tls-cipher line in the ovpn file in various places as suggested by googling, but it had no effect on the error.

Can you please confirm which specific version of OpenVPN is being used on the client device?
There is a long conversation on the forum regarding how the version of OpenVPN host bundled in Orbi routers is not compatible with OpenVPN current standards.
The consensus appears to be that customers have two choices:
- Use an out-of-date version of OpenVPN Client to connect, and live with the potential security implications, or
- Find a different method to access the Orbi LAN than using the OpenVPN host included with the Orbi router.
(For example, there are devices which can be placed on the Orbi LAN, such as the GL-MT2500 Blume 2 device (https://www.gl-inet.com/products/gl-mt2500/ ) or a version of OpenVPN or Wireguard can be run on a device on the LAN (I have installed Wireguard Host on a Raspberry Pi, which works)
