The issue was investigated by RDC support team and the case is closed with the following resolution comment:
"The possible root causes are network/firewall issue, ADS is down, ADS server is shutdown, ADS does not response. The actual root cause cannot be determined due to lack of RFA trace log."
Do you mean the RFA Java application is disconnected from the Refinitiv Real-Time infra, but on the infra side (e.g. ADS server) is still working fine?
If so, could you please give us more details about when the problem occurred?
You can configure the following RFA Java configurations to enable the log file
