When using the node driver, notarisation in flows hangs with a handshake failure - intellij-idea

Question

Whenever I try and test using the node driver, I find at the point of notarisation, my flows will hang.
After examining the node logs, it shows that the notary's message broker was unreachable:

While the notary logs display the following:

How do I fix this?

Answer 1

IntelliJ Ultimate ships with the Yourkit profiler, which by default starts when IntelliJ starts and listens on port 100001 - the default port for the Notary in Driver.
You can locate the config for this using here and alter it to use a different port as per this
Your new config line will look something like this:
-agentlib:yjpagent=delay=10000,probe_disable=*,port=30000
