Getting Initialization timed out after the RHEL 8 upgrade

Hi, I am using Real-Time-SDK-2.0.1.G1 (C++, EMA) and initially my app was running in RedHat 7.9 and it was connecting to RTO feed successfully. But after RedHat 8.4 upgrade, app is not connecting to RTO with following warning. What could be the reason ?

It could be network or firewall settings. Please make sure that you can establish connections to the RTO servers on the RHEL8.4 machine.

You can also try to use the new version of RTSDK 2.0.5.
