Cannon account connection problem on NT8 using Rithmic

[Maurinho79]

Hello, I have an account with Cannon Trading that uses Rithmic, I tried configuring the Rithmic connection on NT8, the connection is successful (in fact I get the green dot for successful connection), but my account does not appear in the list of accounts.
If I log in directly through Rithmic Trader Pro, however, I see my account correctly.
Is there a reason or solution to this?
Thanks in advance to everyone.

First of all thanks for the answer, can you be more specific about it (forgive me).
