Ok. I see you used the standalone option in the past so your renewal conf uses that for "renew" command. It won't work with apache running and standalone is harder to use with web servers in general. So, we want to change that.
Your dry-run test of this worked. So, try this command again but leave off --dry-run. That should get an actual cert and update the renewal conf file to be webroot.
certbot certonly --webroot -w "(your path)" -d ubismartbackend.com
