Installation script fails due to 403 error while downloading ejabberb
Installation script currently fails due to a 403 being returned while attempting to download ejabberd.

First encountered it yesterday afternoon, and have retried a number of times since. Appreciate this is probably an issue on the external server, but thought I'd raise it.
Thanks
I'm having the same issue and therefore cannot finish the installation.
EDIT: I was able to workaround the issue by editing aenigma/functions and replacing all occurrences of https://www.process-one.net/downloads/downloads-action.php?file=/ejabberd/19.05/ejabberd_19.05-0_amd64.deb with https://www.process-one.net/downloads/downloads-action.php?file=/19.05/ejabberd_19.05-0_amd64.deb (there is one "ejabberd" directory too much, they must have changed it at some point).
Note that the setup has then to be run with bash aenigma/setup -dl -pl to make sure the manual changes don't get overwritten, as stated in another open issue.
