Restore to new box failing

I am trying to move from ubuntu 14.04 with miab .30 to ubuntu 18.04.1 with miab .40. I have the server setup the same as the old one same ip name and all. I install miab and it installs without a problem. I don’t go to the admin console because I want to restore it first. I run I copy the backup and secret key to a folder inside of tmp I then run the commands to do the restore all goes well except for the certificate file says one is there already. I then run sudo mailinabox and go through the commands and I get the error below.

Installing Nginx (web server)…

FAILED: service nginx restart

Job for nginx.service failed because the control process exited with error code.
See “systemctl status nginx.service” and “journalctl -xe” for details.

and I can’t get to the admin console what am I doing wrong.

Thank you

Nginx is not starting …

from the command line enter the following and paste the results here:

sudo systemctl status nginx.service

and

sudo nginx -t

From another thread …

Also, I needed to retain the new user-data/ssl, rather than that from the backup otherwise nginx failed to restart.

What error did you encounter with the SSL certificate and what if anything did you do to solve that?

@urbifex can you offer any insight please?

sorry I ended up just going the route of backing up the email in a pst then importing it into the imap connection. So I have it fixed now and working
