Better error message for "Realtime online functionality is not supported on this version of the game"

[cihe13375]

Occasionally I see this error message when launching the game (and apparently I am not the only person experienced this):

Realtime online functionality is not supported on this version of the game. Please upgrade to the latest version.

The frustrating thing is that we are already on the latest version (lazer or tachyon)!

I think the problem is that this error has multiple causes. One reason I have seen is the miss of AuthNative.dll in C:\Users\username\AppData\Roaming\osu (which is not where my lazer data locates, btw). In this case it's downloaded automatically, and a restart brings things back to normal. So the message should be something like

A component of the game is missing, and some online functionalities are disabled. Please restart the game to fix this.

Maybe there are other reasons as well, e.g. network issues. In that case it should be

Connection to [domain] failed. Online functionalities would be limited.

Could you attach logs from the game? I'm told it should not require a game restart for AuthNative.dll to update.

1776069107.runtime.log

Basically it can be reproduced by deleting AuthNative.dll in C:\Users\username\AppData\Roaming\osu and then starting the game

This may be resolved in the next release, please let us know.

I tried the latest tachyon (2026.509.0), and I still can reproduce it by deleting AuthNative.dll, and the error message is still the generic "realtime online functionality ..... please upgrade to the latest version", and it's still fixed by another restart of the game. So I think nothing has changed.

When I said next release, you may need to wait for a full lazer release, not tachyon.

Tried 518.0 and this particular case seems to be fixed; that is, the restart is not needed anymore. However, I am not closing this discussion, as the original issue (confusing error message) is still there, and we still see players reporting this from time to time.

i found another thing that can cause the “Realtime online functionality is not supported on this version of the game. Please upgrade to the latest version.” error, but it’s weird and i think other people are unlikely to hit it.

in my auth.log, i had “[verbose]: Failed to load module:System.Exception: /home/delan/.local/share/osu/AuthNative.so: failed to map segment from shared object”, which i tracked down to the filesystem containing my osu! user data folder being mounted with noexec. this is because i had noauto,user,exec in my fstab(5), and apparently user implies noexec, but it seems you can’t always turn exec back on without just removing user.

anyway if you run the command below and see noexec, this is why your realtime online functionality is broken:

$ findmnt -cT ~/.local/share/osu
TARGET       SOURCE      FSTYPE OPTIONS
/path/to/osu path/to/osu zfs    rw,nosuid,nodev,noexec,relatime,xattr,posixacl,casesensitive

but if you run it and you do not see noexec, your realtime online functionality is broken for some other reason:

$ findmnt -cT ~/.local/share/osu
TARGET       SOURCE      FSTYPE OPTIONS
/path/to/osu path/to/osu zfs    rw,relatime,xattr,posixacl,casesensitive
