Currently, it looks like tickets is registered as an alias and, presumably, the new server certificate is specific to issues.
@cintiadr, how hard would it be to configure this server for a tickets.openmrs.org letsencrypt cert as well? All ticket URLs should ideally redirect to equivalent issues URLs.
We could do a redirect in dnsmadeeasy; however, I don’t believe that would support https://tickets.openmrs.org redirects as desired.
