Describe the bug After deploying the letsencrypt certificate used for the opnsense router to the Unifi Controller plugin using the os-acme-client plugin's "update local UniFi keystore", the os-unifi-maxit plugin is not starting anymore.

To Reproduce Steps to reproduce the behavior:

1. Go to 'Services > ACME Client > Automation'
2. Create an automation with command "update local UniFi keystore", leave path to "/usr/local/share/java/unifi/data/keystore", call it "UniFi_automation"
3. Go to "Services > ACME Client > Certificates"
4. Click "edit" next to the certificate used for the opnsense router, add the "UniFi_automation" to the automations, click "save"
5. Click "run automations" next to the certificate where you just added an automation.

UniFi doesn't start anymore.

Expected behavior UniFi Controller should come backup with a new certificate. @adn77 maybe you have an idea?

Relevant log files I need some support to understand where the logs are.

Additional context Router certificate is a wildcard certificate, public key is of type EC384.

Environment OPNsense 24.1.6 amd64 os-acme-client plugin 4.2 os-unifi-maxit 1.3

Interestingly, even after uninstalling and reinstalling the os-unifi-maxit plugin, it still crashes almost immediately after being launched.

I checked the /usr/local/share/java/unifi/logs/startup.log file, but there is a single line:

[2024-05-16 18:19:08,561] <launcher> INFO  startup - Initiating startup

I moved the entire /usr/local/share/java/unifi/ folder (somehow it's not removed when uninstalling the plugin), I rebooted opnsense, but still impossible to keep the UniFi service up and running, this is weird, something has been corrupted that the plugin uninstallation is not removing it seems.

Maybe @mimugmail you have an idea where I should look?

Remove the plugin, remove the folder and install again. Please use issue tracker at my repo, unifi is not official nor supported :)

Thanks for the feedback.

I was not sure if the issue is with the "update local UniFi keystore" command of with the UniFi plugin. Plugin was working fine until I tried to deploy a cert to the keystore.

I did move the /usr/local/share/java/unifi/ folder and removed the plugin, it does not help unfortunately.

I will open an issue on you tracker, thanks.

This occurence issue is fixed by changing the port number crowdsec is using for its LAPI interface. Many thanks to @mimugmail.

I cannot reproduce the issue anymore and while I do not have an explanation for the fact that UniFi Controller never had a conflict with crowdsec before, it is clear that I had a misconfiguration.
