How to configure OpenVPN to work with two WAN IPs?

Question

openvpn

Hello There!!!

There are inputs:
Two white external IPs from providers (1.1.1.1 (IP 1) and 2.2.2.2 (IP 2))
One MikroTik CCR device (configured and configured correctly, there is port forwarding on two white addresses, also available on two WANs)
One OpenVPN Server on Debian 10
One (or more) OpenVPN Client

The essence of the task:
It is necessary to configure the server (or client) so that if the connection is lost on IP 1, the client will reconnect (Automatically!!!) to IP 2.

Actually, the question is where to climb and look at all, I studied the available options on the network for similar requests, but did not find the exact answer, and the official OpenVPN forum has an article on this topic, but it did not help, it just says "Add proto IP 2: 1194 "As it turns out, it doesn't work.
Tell me where to dig completely broke his head already.

I will answer questions and subtleties of settings, if necessary.
