Hi,

i use EIKON .NET API for real-time data subscriptions. My application launch 3 real-time data subscriptions and those subscriptions running as long as my application is running (from 9am to 5pm).

After some minutes/hours, i encounter an internal API error which is a something like a quota limitation usage. This is the API log when the error occurred:
