We recently changed the hostname pointing to this jira instance from https://jira.carenetprojects.nl/ to https://tickets.macketmar.com/ . We followed the procedure here and the rest of Jira seems to be functioning but it might be related.
Via the old hostname the listing does return but the rest of the Jira install gives warnings.
