Did you read your Clients log file?

You have set myCa as server certificate on your mikrotik instead of the server certificate..

Maybe you need to try another VPN service? I use OpenVPN GUI 2.4.7 and it works Just great.
VPNs with router support

I think it is rather a misunderstanding on your side of what the OP's problem is.

There are two uses of VPN:
  1. the one for which VPNs were originaly invented, i.e. to allow encrypted access to your own networks via internet,
  2. the one which most home users know as VPN today, which is to hide the pages you actually surf from your ISP and/or the authorities, or to hide your actual IP address from the services which apply geographical policing (so you cannot use your Netflix subscription while you stay in another country).
As the OP claims an issue where Mikrotik is on the server side, he most likely deals with case a., so replacing the VPN provider is not an option. Theoretically, he may have a Mikrotik running at home to be able to watch Netflix while abroad, but in this case a public VPN service may still not be a sufficient substitution as the content provider guys are no idiots either so they often block access from IP addresses known to belong to public VPN providers.
Instead of writing novels, post /export hide-sensitive. Use find&replace in your favourite text editor to systematically replace all occurrences of each public IP address potentially identifying you by a distinctive pattern such as my.public.ip.1.

ovpn-server config:
cipher: blowfish128,aes128,null

client.ovpn:
cipher AES-256-CBC

The parameters must have common values,
such as 'cipher=aes256' for the server and 'cipher AES256' for the client.
