------------------------------------------------------------
[~efalke] I suspect what you may be encountering
https://issues.apache.org/jira/browse/NIFI-9548 but I'm not sure.
Would recommend giving a newer version a try, or when you're in this state
capture a thread dump ( {{bin/nifi.sh dump thread-dump.txt)}} and attaching
that here. From that, we can better understand what's happening.

> NiFi 1.15.2 -- GUI freezing when remote process group loses connection
> ----------------------------------------------------------------------
>
> Key: NIFI-10526
> URL: https://issues.apache.org/jira/browse/NIFI-10526
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core UI
> Affects Versions: 1.15.0
> Environment: Redhat 7.9
> Reporter: Evan Falkenstine
> Priority: Major
>
> When my Remote Process Groups lose connection to the distant end the NiFi GUI
> freezes and won't let me stop/start processors or create new objects. I'm
> able to interact with the GUI such as context menus but none of the actions
> go through. I can use the context menu to disable the RPG but it takes 10-15
> minutes for the disable action to apply, lining up with the rest of the GUI
> "unlocking". Restarting NiFi does not help to break the connection enough
> because during bootup it starts the connection attempt before I can stop the
> RPG. I've had success with editing the flow.xml.gz file and changing the RPG
> to disabled and restarting NiFi. This happens 100% of the time on NiFi 1.15.2.
