nginx-proxy companion SSL generating issue.

The following message has bothered me for quite a while. One thing I didn’t realize is that I have to run companion after nginx-proxy.

If I recreated nginx-proxy, I have too recreate companion too.

The reason is that when companion is created, it will mount the columns created by nginx-proxy. Because I recreated nginx-proxy without recreating the companion. I see the following message quite a lot.

Although I recreated companion after nginx-proxy, I still see the following message for some of my sub domains. Why not work? Still a myth.
