Tasks 0.16.0 is compatible with NC 28 and above. There seems to be something wrong with your server (configuration).

You can try to remove the app and reinstall it again. Clear the caches, restart your server and check the access rights in your apps folder. If this doesn't help, please ask for support in the forum.

@Bazis007 I used "occ app:enable tasks" to enable it via command line and it seems to work fine now.

[Bazis007]

@sjiawjbssj Thanks for advice. I was try to enable this app via command line. Apps is shown as enabled, but I see only nextcloud template, when click to tasks icon. I also try to make "fresh" install of nextcloud with lates versions, but got same problems.
I unable to enable tasks, calendar and many other apps. May be something was broken in NC. I don't know.
I am use docker compose for installation.

@Bazis007 sadly that's beyond my knowledge. Maybe someone in the nextcloud forum can help you.

UPD: Fixed by adding "proxy_redirect http://$host https://$host;" on my reverse proxy (nginx).
Thank you for support.
