So from the nginx-and-vue server, you can access vue.

That seems to show that from a different machine, you can access nginx,
which reverse-proxies to vue; and the content from vue includes links or
redirects to localhost (and to localhost:8080). And those links will fail.

I cannot tell from these pictures what one http request was made and what
response was received -- maybe the output of "curl -vk https://ggc.world"
from this machine will show something?

If the issue is that vue is returning a http 301 or 302 redirect to
something below localhost or localhost:8080, then either changing that
in vue, or adding proxy_redirect in nginx, may be best.

If the issue is that vue is returning a http 200 with content that links
to localhost, then that should be changed in vue.

I suspect that almost anything in the vue config that mentions localhost,
should be removed. But vue people may be a better source of information
there.

Good luck with it,
