Code admin not accessible under UCS 5

I’m trying to open /loleaflet/dist/admin/admin.html , and it doesn’t accept username/pass that were defined at CODE app configuration. CODE itself seems to work, but not admin. Tried to change password many times already.

Do you have an Apache reverse proxy set up, and if so, which version? It might be a duplicate of these in that case:

I think it’s not the same, as I get a basic authentication prompt, but it doesn’t accept the password I’ve configured at app settings…

ok, I’ve installed a fresh UCS and CODE, and now admin works. Maybe it was related to upgrades, as I’ve started from old versions before that…
