@pepicheck The second option DID NOT WORK!! Only the first option worked.

I added the tls-cipher TLS-DHE-RSA-WITH-AES-128-CBC-SHA to the generated .ovpn file (above and after cipher AES-128-CBC) and then importing to settings but it did not work

 

client
dev tun
auth-nocache
proto udp

cipher AES-128-CBC
tls-cipher TLS-DHE-RSA-WITH-AES-128-CBC-SHA
comp-lzo adaptive

Device Firmware Version:1.18.0 0.9.1 v009e.0 Build 241018 Rel.43535n 

Device Hardware Version:Archer VR2100v v1 00000000

 

Any idea why the option 2 did not work for me?

  @ELAMeri Error message? Distro what you have???

 

Same error on a MacBook running Sonoma 15.3

Eventualy reset the OpenVPN client settings to defaults and the issue was solved.

But what puzzled me is that the same OpenVPN setup on multiple Omada controller setups - and only one of them was returning the error message, using the same OpenVPN client app. Of course, all controllers updated to the latest version.

At least it's fixed.

Hopefully this will help someone in the near future.
