Cloudron Forum

@pixeltablet as long as the DNS settings are copied over to cloudflare, everything will continue to work.

You can also make Cloudron add the DNS entries into Cloudflare by first switching to cloudflare and then sync DNS - https://docs.cloudron.io/domains/#sync-dns . Just so you don't hit any DNS issues, you can add the 'my' subdomain record manually into Cloudflare.

@grimreaper said in cPanel DNS:

Wow, what is his problem?

I know it is unrelated but since @mhgcic brought it up is Lamp easier than cPanel to use? is there a GUI for it?

Cloudron does all that cPanel does and more. There's no need for cPanel with Cloudron. Yes, with GUI when necessary. Basically, your cPanel account comes empty just as a LAMP installation is.

Not sure if relevant to your situation, but to bypass specific DNS entries you can also do:

local-zone: example.com typetransparent local-data: "my.example.com A 172.18.0.1"

For namecheap, look at their docs - https://www.namecheap.com/support/knowledgebase/article.aspx/434/2237/how-do-i-set-up-host-records-for-a-domain/

@girish Thank you!

@Jan-Macenka The sync dns also syncs the mail related dns settings. There should also be an event in the eventlog indicating the dynamic dns updated your dns (or not). When things are going out of sync, can you check what it says in the event log?

@j_vmess your domain works just fine for me here. Maybe it's a browser cache issue? Have you tried another browser or after clearing the browser cache? I removed your domain from the original post, since it was showing the setup screen.

@AartJansen for new apps, AAAA is automatically added. For existing apps, go to Domains -> Sync DNS.

@nichu42 said in DNS resolving problem:

I've tried to modify the forward-all.conf like this

forward-tls-upstream: yes forward-addr: 91.239.100.100@853#anycast.uncensoreddns.org forward-addr: 1.1.1.1@853#cloudflare-dns.com

but it didn't work (SERVFAIL).

Answer to myself (in case someone else ever needs this):

It is necessary to also add the following to the conf file:

server: tls-cert-bundle: /etc/ssl/certs/ca-certificates.crt

so the validity of the certificates can be verified.
After that, you can add TLS upstream servers as mentioned in my previous post. I've decided for anycast.uncensoreddns.org and dns.quad9.net now.

I figured out my issue. Turns out that even though I read the documentation I made one critical mistake right at the beginning. I had to create my email accounts and the addresses I wanted to work in Cloudron first. Then Install the Snappy mail client and set up the email accounts there second.

Once I deleted the Snappy mail client and reinstalled it everything worked. I'm not sure how but this topic can be marked as resolved.

I went and checked our instances' logs. I found sporadic ENOTFOUND but very spaced out (like months apart).

@girish thanks for the explanation! Yeah the change happened ~14 hours ago and the TTL was set to 24 hours I reckon. I'll just wait until tomorrow to continue 😉

My plan would have been to lower the TTL a few days prior to the A record, so the caches would invalidate sooner.

@jdaviescoates said in Installed at map.bridport.coop then deleted, then reinstalled on same location: server not found:

Is there a way to flush the NXDOMAIN cache on routers/ computers?

Not that I am aware of. These days browsers also do their own DNS caching complicating things even more.

@girish ok, sounds good to me.

@girish thanks, that worked 🙂

Hey y'all. Used another domain I had that was correctly propagated. It's perfect. Now I gotta wait for my DNS records to update before I do the switch!

@prusaman If the instance has no IPv4, how do you ssh in ? Via a jump host?

@redegelde said in server cloudron install ubuntu 22.04:

The fiddle was after installing Cloudron.

Cloudron tells you not to do so in the banner if you login over SSH after installation ^^ Everything you can do or change is documentated in the docs.

@redegelde said in server cloudron install ubuntu 22.04:

What is/are the good workaround to move from one to other vps

The easiest way for a fresh installation is setting up a new VPS with Cloudron and restore from a recent backup during setup.

For migrating Mastodons user management I can't give you any advice but there are various topics regarding this if you look through the Cloudron forum.
