Lets Encrypt Problem with multiple public IPs

[mts]

Hello guys,

I have the problem, that Let's Encrypt is not working with multiple public IPs.
I'm using haProxy on our external server IP (xxx.xxx.xxx.68) but let's encr. is calling out  with xxx.xxx.xxx.66

How can I force let's encr. to use another external IP to make the requests?
