Login Rejected. Watchlist size of 250000 for 'RSSL' connection is outside of range [15001, 100000...

...] supported for this ADS fanout tier for this type of connection

Hi,

I am getting warning in the title whenever i am trying to connect with Realtime Optimized. Is it completely governed by the watchlist type i am connecting to ? Or can it be due to connection type as well ?

Hi @thilinaillangasinghe ,

As my colleague answered in this question,

The issue may be related to the specific endpoint tier you are connected into. Based on the response, your account setup would not allow you to properly manage a watchlist based on your watchlist license. Refer to this question

and also there's an answer here

You are not using the correct tier endpoint for which your MachineID has been licenced.

You are trying to connect to a Large Tier endpoint but only licenced for the Small tier.

Ideally, you should use the service discovery example - which will automatically identify endpoints matching your licence and region location- websocket-api/market_price_rdpgw_service_discovery.py at master · Refinitiv/websocket-api (github.com)

If they are using an MRN example that hardcodes an endpoint, then they can combine the Service Discovery code from the above example with the MRN example.

Another option (not recommended) is to select a valid small tier endpoint from the list of endpoints:

Hope this helps and please let me know in case you have any further questions.

Thanks for the response @raksina.samasiri , What is the connection between Tier sizing (Watchlist size) and number of RICs(and fields) i am subscribing to ?

Hello @thilinaillangasinghe

I highly recommend you contact your Refinitiv representative to check this information for you.

Note: you need to provide your Machine ID to the team too.

Hello @thilinaillangasinghe

If you use the Service Discovery, the API/SDK automatically connects to the RTO server that matches your subscription tier.

Please try the Cons450 (EMA C++) or ex450_MP_QueryServiceDiscovery (EMA Java) example.

Thanks for all the replies. In my case as it seems, i've been using same RTO account details in multiple systems. As a result collective watchlist size exceeds account limit.

Still not clear how should i decide to which watchlist size i should be subscribing to based on number of RIC and field count i am subscribing to.

Is it, (Total RIC count x Field count)?

Hello @thilinaillangasinghe

Based on the Refinitiv Real-Time - Optimized Install and Config Guide document, Refinitiv defines VIPs by tier, region, and availability zone. The RESTful call to Service Discovery auto-filters by tier, using the maximum number of items (known as max-watchlist) as specified by your Machine ID configuration.

I highly recommend you contact your Refinitiv Representative to check your total subscription RICs with your tier.

Regards to the "i've been using same RTO account details in multiple systems." message. Please be informed that if you are using the Version 1 Authentication (Machine-ID GE-A-XXXXXX-X-XXX), it is not advisable to use a single Machine-ID with multiple sessions/applications. I highly recommend you reach out to your Refinitiv representative to get multiple Machine-IDs if you want to run multiple applications/sessions.
