I have recently installed NiFi, and it was working fine for few days. But suddenly today when i try to open it using run-nifi.bat, the NiFi window is getting closed in few seconds stating the below error:

I do looked out for the org.apache.nifi.StdErr Failed to start web server: Must configure HTTP or HTTPS connector error, but unfortunately I cant find a similar one. I'm sure that no settings or properties has been changed since installation. Any suggestion guys?
I was getting the same error.
You need to check nifi-app.log file to get more details on this type of error.
Here’s what I did: Remove the port information from nifi.properties for HTTPS and only keep the setting for HTTP. Then restart nifi again.
Keep one property enable like https or http. in my case https:127.0.0.1:8443/nifi/
it works fine me.

I am just a beginner and trying to install NiFi for first time. I am having problem getting it working.
I have Windows 7 32 bit. I have installed LibericaJDK-19 just to get Nifi working. Else it was not working with java 8 as well for me.
I am trying nifi-1.19.1. conf file is default. I have set JAVA_HOME to point to new JDK - 19.

When I run run-nifi.bat it pops up for a split second but then auto closes. I don't really understand this, I just need it for a university class and it hadn't been properly explained, so I'm just trying on my own really.
I get this in my nifi-app.log:

I've tried editing the web properties in the config files in case the default was wrong. Right now it's on, but the errors are the same:
nifi.web.http.host=localhost
nifi.web.http.port=9090
nifi.web.http.network.interface.default=
I have Windows 10 Home Edition.
NiFi requires Java 8 or Java 11 to run. So your environment variables should point to the correct directory with Java 8 or Java 11.
Have you tried setting the JAVA_HOME environment variable? I would recommend checking the config files and telling the configs where to find the Java installation
You might be missing URL ACL
Maybe you can try below command:
netsh http add urlacl url=http://computername:port/ user=username

I ran into this issue when the folders pointed to by nifi.nar.library.directory.* was inaccessible, e.g. the Symbolic links were no longer valid due to file system changes.
Fixed the links and the server came up.
sudo chown -R nifi:nifi /opt/nifi/
sudo service nifi start
worked for me.
I'm only attempting to launch the Nifi UI as a local instance to start playing with it. I've unzipped the package and made sure to set the JAVA_HOME variable to my Java 1.8. When I try to bin/run-nifi, in my nifi-app log, the error message is:

I've followed the installation instructions and haven't been able to trouble shoot. How do I load these NAR files upon running Nifi?
Thanks
I believe the underlying error in your output is java.io.IOException: Z:\DoE\LOCAL-~1\NIFI-1~1.0\.\work\nar\framework could not be created.
NiFi requires file permissions to create and write several directories, there is a list in the NiFi Admin Guide: How to install and start NiFi. NiFi does this to unpack the NAR files, write logs, and for various data repositories that comprise your data flow.
You have a few options:
Modify the permissions of the directory to allow NiFi read/write access. This can be done for each individual child directory.
Copy the entire NiFi distribution to a read/write location and run it from there.
Edit the conf/nifi-properties file to change the locations of these directories to read/write locations. See NiFi Admin Guide: System Properties for help on the properties.
Symlinks are a great solution for systems that support symlinks.
Two things you can try:
Run NiFi with administrator privilege (not a good practice) by going to ~\<NIFI_INSTALLATION_DIR>\bin and right click run-nifi.bat. Click Run as Administrator
Move NiFi directory to a location where the logged in user has full access to. Ex: C:\Users\<YOUR_USER>\Documents\. Now try to execute bin\run-nifi.bat
Similarly to the resolution that James proposed. I had to do the below 3-step process.
My scenario: I'm using docker containers and had the same problem. Even changing the user of my container to root didn't work. So, I did the following:
1 - Download Minifi https://nifi.apache.org/minifi/download.html
2 - Untar and execute the Minifi agent on my own laptop (I'm using MAC) so that the necessary folders and files will be created.
3 - Tar it up again and add to the DockerFile of my container creation
Done! Everything worked fine after that.
iam trying to connected to remote broker url in activeMQ (activemq installed in unix vm)
iam able to connect from browser from my laptop.
while running springboot iam getting this error
--- [ActiveMQ Task-1] o.a.a.t.failover.FailoverTransport : Failed to connect to [tcp://http://199.247.18.11:61616] after: 8 attempt(s) continuing to retry.
what could be the issue?
Please remove https:// from your connection string. Port 61616 is expecting JMS connections.
Your connection string should be tcp://199.247.18.11:61616 or something similar. There is a rest API that (I think) goes through the built in HTTP server but it's not going to listen on 61616 and it's going to have a much longer URL. Something like
http://admin:admin#localhost:8161/api/message?destination=queue://myqueue
