No it is not related to that bug. That bug only occurs if you are creating a new x509 root/host certificate set for the OpenVPN Server in CU183, ie a first install of OpenVPN or the wiping away of all existing client connection certificates and the existing x509 root/host certificate set.
The image shown is for a client and it does not like some of the options provided in the .ovpn. Those have been present for a long time.
There have been some other posts about openvpn clients of a certain newer version no longer liking the auth-token and/or the auth-token-user entries. Have a search through for them.
These are used for the OTP option if that has been selected.
If you are not using OTP then try remove\ing those auth-token* entries from your clients .ovpn file.
