We get "No connection or service is currently up that supports this request" on RTC Access

We have multiple RTC Access's connecting to multiple ADS to pull data, sometimes we get "No connection or service is currently up that supports this request" when pulling data using the RFA OMM Viewer. Users have also reported issues in Workspace. We then have to restart the RTC Access for it to work

Hello @sidath_wijeratne
This kind of issue needs to be investigated on both API and RTC server sides. If you are the RDC named user, I strongly suggest you contact the Real-Time APIs Support team via https://developers.lseg.com/en/api-catalog/real-time-opnsrc/rt-sdk-java page and click the "Contact premium support" button on the page.
Please also specify the RFA edition (Java, C++ or .NET) and version that encounters the issue.

Thank you for reaching out to us.
If the problem happens with both the RFA OMM Viewer and Workspace, and restarting RTC can solve the problem, the cause of the problem should not be in the API. You need to contact the RTC or infrastructure support team to investigate this issue.
As this forum is more for programming type queries, rather than product queries - I would recommend you raise a 'I need help using the product' ticket with our helpdesk. That way a product specialist can work closely with you to investigate this issue.

Thank you both, I have opened a support ticket but was checking in addition to that as root cause was not yet found.
