[Exist-open] apps from launcher not working on new install

[Hayim L. <hl...@um...>]

Hello,
I just installed eXist 6.3 on an aws linux machine running on port *8081*.
The database loads and I can log in as admin.
All the default apps that appear on the launcher yield errors like:
HTTP ERROR 404 Document /db/apps/eXide not found

I have been able to use the package manager to load and run an app
(TEI-Publisher), but other apps created by me and working in a docker
instance generate the following again caused by being unable to access /db:

> err:XPST0017 error found while loading .... for module:
> /db/system/repo/tei-publisher-lib-4.0.1/content/tei-functions.xql [at line
> 84, column 13]


There is another version of exist (4.7.1) running on port *8080*. Could
this be the cause of the problem?

Any suggestions about how to fix this?
Best, HL
