onesync
There are more ways to enable onesync so let's take a look at how to do it in two ways.
✅ How to Enable OneSync (2025)
By putting the command in server.cfg
# enable OneSync (required for server-side state awareness) set onesync on
By putting startup command
+set onesync on
If we done everything correctly we can check the final result by command onesync in server console

The onesync has to be always on "on" if there is "legacy" or "off" that's bad and the resources will not work.
🔍 How to Check if It’s Working
In your server console, run:
onesync
You should see something like:
"onesync" is "on"
⚠️ Know issues:
txAdmin can override the
onesync
setting, especially if the startup parameters are defined differently in the txAdmin panel.If
set onesync
appears multiple times (e.g., instart.sh
,txAdmin.json
,server.cfg
), only the last one loaded will apply.Make sure no other config accidentally sets it to
"off"
or"legacy"
.
