@girish Thanks. I'll take this up with Vultr.

I continue to get the following alert from my ISP (Vultr.com, where shared servers are called "instances")

Recent network security audits have detected some issues on your instances. Please review the following reports and help us to ensure the security of our network:
== Portmapper servers ==
Portmapper is a service usually used with NFS. When this is not properly firewalled, it can be abused to conduct DDOS attacks. We recommend that all portmapper services be behind a firewall, and restricted to only IPs that need to contact them.
For Linux machines, please add firewall rules to block port 111 on both UDP and TCP:

iptables -I INPUT 1 -m tcp -p tcp --dport 111 -j DROP
iptables -I INPUT 1 -m udp -p udp --dport 111 -j DROP

Please see https://blog.cloudflare.com/reflections-on-reflections/ for more information on reflection attacks.

The following IPs have been detected running open portmapper servers:
[my cloudron IP was shown here]
If you believe these reports to be false positives, please let us know.

How should I address this?

@nebulon Thanks. If I keep having this issue I'll start troubleshooting as you suggest, and will probably try to get the Vultr support people involved as well.

@girish Thank you. I'll save these comments for the next reboot. Is it possible that there is some wrinkle in the way Vultr provisions the instance? If so I want to alert them to it.

Update: a repeat of a restore of a backup has it running again. Just a day's worth of emails gone.
How can I reboot in the future without all this agony? Only from a terminal? I'm never going to use the on-screen "reboot now" button again.

It didn't work. The backup from 9 this morning has been restored, but the Cloudron install still refuses to boot.
I'm now going to have to install a fresh Cloudron and painstakingly re-install everything (losing all my email records in the process. It will probably entail a complete re-working of all my Cloudflare settings.

Surely this isn't normal.

I'm now restoring the Vultr backup taken this morning at 9 am. I was never able to get my Cloudron installation to run following the reboot -- all it did was show me the red bar with the "Cloudron is rebooting" message, even though when I used the Vultr instance console it was obvious that Ubuntu had completed the reboot and was ready.
This is the third time I've had to do this. What am I doing wrong?

How long should a reboot take? I have had to restore from backups twice now after experiencing what seems to be an endless reboot that appears to never finish.
It seems to be happening again (9/28/2021).
Am I just being impatient?

@girish Thanks!

I have limited experience setting up LAMP, and what I know I learned from DigitalOcean tutorials.
One of their tutorials includes this on editing the DirectoryIndex directive in mods-enabled/dir.conf:

/etc/apache2/mods-enabled/dir.conf
<IfModule mod_dir.c>
DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm
</IfModule>

By moving "index.php" to the first position in the DirectoryIndex directive, I can cause index.PHP to run as the default rather than index.HTML.

I realize I can just remove index.HTML if I want index.PHP to be the file that runs, but I wonder, is it possible for me to edit a DirectoryIndex directive somewhere, as per the tutorial?

That would let me keep an index.HTML file on the site as a fallback in case PHP failed (unlikely, but surely possible).

@girish Thanks -- I discovered this, finally. Don't know why I didn't see it immediately.

I was unable to get my Vultr one-click Cloudron to do anything, so I created another, assuming I had misconfigured something. Now when I try to use the second one, I am unable to register in the app store because "an account by that name already exists" which seems strange. I know it exists, and I'm trying to log into it. Not sure why I can't log into an account that exists because the account exists.
But since it doesn't work, my guess is instead of allowing me to re-install with an existing account, you are requiring me to have a new account, so now I apparently have two somewhere down in the bowels of your software.
Can you please merge them so I can get to work on trying to set up Cloudron on a Vultr server?
