could you please check the changelog at
https://github.com/OpenVPN/openvpn/blob/dco/Changes.rst whether some of
the options described there make any sense to you?
I'm especially thinking of
Compatibility mode (--compat-mode)
The modernisation of defaults can impact the compatibility of
OpenVPN 2.6.0 with older peers. The options --compat-mode allows UIs to
provide users with an easy way to still connect to older servers.
Could you set
verb 2
I'm hoping to find some clue in the data pushed by the remote side.
Best Regards,
Bernhard
