JMeter freezes when you run the test from remote server

Question

1. On my remote host I am running jmeter server ./jmeter-server
2. I have kicked the jmeter from my local machine using this command ./jmeter -Jremote_hosts=Remote Host IP
3. GUI Pops up
4. Open my test.jmx and Run->RemoteHost->RemoteHostIP
5. At this time, jmeter freezes, I was unable to do much after that my test had 1 thread, 60secs ramp, run 1 time

Any idea why is it frozen and I am not be see any test results. I do not have any listeners except "View Results Tree"

Answer 1

I faced the same issue. In my case, it was due to the firewall (ufw on ubuntu). After stopping the firewall I was able to run the tests normally.
