Artifactory service fails to start upon Fedora 35 reboot

I have installed on Fedora 35 jfrog-artifactory-oss (v7.31.11-73111900.x86_64) and enabled it as a system service to start at boot. But whenever I boot up my OS, the server never starts properly. I will always need to kill the PID of the active running Artifactory process. If I then do sudo service artifactory restart it will bring up the server cleanly and everything is good. How can I avoid having to do this little dance? Is there something about OS boot up that is causing Artifactory to get thrown off?
I have looked at console.log when the server is not running properly after bootup, I see some logs like:
2022-01-27T08:35:38.383Z [shell] [INFO] [] [artifactoryManage.sh:69] [main] - Artifactory Tomcat already started
2022-01-27T08:35:43.084Z [jfac] [WARN] [d84d2d549b318495] [o.j.c.ExecutionUtils:165] [pool-9-thread-2] - Retry 900 Elapsed 7.56 minutes failed: Registration with router on URL http://localhost:8046 failed with error: UNAVAILABLE: io exception. Trying again
That shows that the server is not running properly, but doesn't give a clear idea of what to try next. Any suggestions?
2 things to check,
How is the artifactory.service file in the systemd directory
Whenever the OS is rebooted, what is the error seen in the logs, check all the logs.
Hint: From the warning shared, it seems that Router service is not able to start when OS is rebooted, so whenever OS is rebooted and issue comes up check the router-service.log for any errors/warnings.

Rabbitmq: Node down

I am getting node down error on rabbitmq, this is happening sometimes.
Able to see the below error when I execute: sudo rabbitmqctl status or sudo rabbitmqctl list_queues
Error: unable to connect to node : nodedown
connected to epmd (port 4369) on host-name
epmd reports node 'rabbit' running on port 25672
can't establish TCP connection, reason: timeout
suggestion: blocked by firewall?
version: {rabbit,"RabbitMQ","3.6.9"}
os: Ubuntu 16.04
I have checked hostname which is ok with me, not changed since the installation
Also able to telnet localhost 25672
What could be the reason behind this error and possible solution?
And one more question, I am checking node status using below API
curl -s GET http://edx:edx#127.0.0.1:15672/api/healthchecks/node/
Is above API ok or not to check the health status of the node? Please suggest if there is anything else. I have set up one shell script which will call this API and if status is not ok then it will restart rabbitmq-server service. Script is executed from cron every minute.
Looks like your rabbitmq node is... down. rabbitmqctl needs a running node to perform these commands.
If you're using systemd, you can check the service status:
service rabbitmq-server status
Or just try to restart the node:
rabbitmqctl start_app
Telnet on port 25672 tells you the rabbitmqctl is running, but RabbitMQ itself does not run on that port (by default, it's listening on 5672).

**Command Used :**
/usr/bin/systemctl restart nginx
**Log:**
Failed to restart nginx.service: Interactive authentication required.
See system logs and 'systemctl status nginx.service' for details.

unable to restart httpd.service on centos 7 after the configuration of openstack-dashboard

Actually I configured controller node having few services like Identity, image, compute and network. After the completion of these , I checked httpd service status and it was active. However I again restart httpd service (systemctl restart httpd.service). At this point it was successfully restarted but when I configured openstack-dashboard then I tried to check httpd status , unfortunately it was in a inactive state. I tried very hard to restart this service through out all possibilities like restart system, enable ,disable or start services, reinstall httpd but I failed. Thanks in advance who will be able to sort out my problem .

Permission denied while using 'Kaa-Node restart'

I am trying on an application and previously it worked and the data was able to be persisted into MongoDB. But recenntly , we had a change of router and thus we went ahead to regenerate SDK and etc but we still has the connection error.
Error :
2017/01/26 9:24:27 [WARNING] [kaa_bootstrap_manager.c:612] (-7) - Could not find next Bootstrap access point (protocol: id=0x56C8FF92, version=1)
2017/01/26 9:24:27 [ERROR] [kaa_tcp_channel.c:307] (-7) - Kaa TCP channel [0x929A2016] error notifying bootstrap manager on access point failure
2017/01/26 9:24:27 [ERROR] [kaa_client.c:240] (-7) - Failed to process OUT event for the client socket 3
And thus , we went ahead with troubleshooting where one of the staffs i emailed passed me a link for troubleshooting .
https://kaaproject.github.io/kaa/docs/v0.10.0/Administration-guide/Troubleshooting/
I followed already but i had an error where im stucked with writing 'kaa-node restart' to restart the node service.
Here are the commands for troubleshooting:
Connect to your Kaa Sandbox via ssh:
$ ssh kaa#<YOUR-SANDBOX-IP>
password: kaa
Stop the Kaa service:
$ sudo service kaa-node stop
Clear the Kaa logs:
$ sudo rm -rf /var/log/kaa/*
Start the Kaa service:
$ sudo service kaa-node start
I typed 'sudo service kaa-node start'. it gave me:
kaa#kaa-sandbox.kaaproject.org:~$ sudo service kaa-node start
* Starting Kaa Node daemon (kaa-node):
/bin/bash: /var/log/kaa/kaa-node-server.init.log: Permission denied
Try verifying the Kaa host on the Management page. Also, the Sandbox Web UI (the Management page) is able to restart all the necessary Kaa services on the Sandbox after the Kaa host change.
Please note that the Kaa host should match the PC host IP address accessible from the network your applications are running in.
Please try and let me know if this works for you.
