I use 3 instances of Sierra Chart on a single PC.

When I add a 3rd instance, I always get the following in the message log, and every 60 seconds there's another attempt at connecting:

2026-09-27 08:20:16.486 | Denali Data Feed | Logon error received from server: Connection limit exceeded. | MaxConnectionsForSameDevice = 3, NumCurrentConnectionsForSameDevice = 5

1. I only have 3 instances of Sierra Chart installed on my PC.
2. I have the setting: Global Settings > General Settings > Always Use 'Data' Folder within Main Folder set to: Yes

Can you please look at the backend to see why I am exceeding 3 connections? Thank you

You actually are using 4 instances of Sierra Chart on your computer even if you are not aware of it. Maybe one of the instances is not visible to you.
