Why connections drop
Even with cloud copying, broker sessions can be interrupted by:
broker maintenance or restarts
authentication/session timeouts on the broker side
network instability between broker infrastructure and their API
login/security events (password changes, permission changes, etc.)
When this happens, Tradesyncer may recover automatically, but some cases require manual action.
First steps (do these first)
Reconnect the broker connection inside Tradesyncer
If it still fails, delete the connection and add it again (fresh authentication)
Confirm the status returns to Healthy/Connected
If you’re still stuck after re-adding, contact support with a screenshot of the connection status and the error message.
Tradovate / NinjaTrader connection issues
OAuth token renewal (what Tradesyncer does for you)
Tradovate uses OAuth-based authentication. Tradesyncer automatically renews your OAuth token as long as you keep the connection added in Tradesyncer.
In most cases, you should not need to “babysit” token refresh.
When you may still need to reconnect
You may need to reconnect if:
Tradovate ends the session unexpectedly and our reconnect attempts do not succeed.
you removed/re-added accounts or permissions changed
your login/security settings changed on the broker side
the connection shows Disconnected and does not recover
Fix
Click Reconnect
If reconnect fails: Delete the connection → Add it again
ProjectX connection issues
Use the correct username (most common issue)
ProjectX usernames are not always your email.
Fix
Open your prop firm dashboard
Go to Profile
Use the username shown there
API key issues
Before connecting:
confirm the API key is linked to the correct ProjectX dashboard / account
copy the full key (no missing characters)
Session limits
If ProjectX logs you out repeatedly:
keep only one active session open
avoid multiple tabs/windows signed into the same account
Rithmic connection issues
Step 1: Make sure the Rithmic agreement is signed
If the agreement isn’t signed and activated, authentication will fail.
Fix
Log in to your prop firm dashboard
Find the Rithmic agreement section
Sign and wait for confirmation/activation before connecting
Common errors and fixes
“Authentication failed”
verify username/password (case-sensitive)
confirm correct System (prop firm environment) is selected
try a different Gateway location
“Already logged in”
Rithmic often allows only one active session per credential.
close any platform using the same credentials (R|Trader, NinjaTrader, etc.)
reconnect in Tradesyncer
“Gateway connection failed”
try a different gateway location
gateways can be under maintenance
