@jordanurbs said in SSL Certificate by Cloudron not trusted:

One thing that might be an issue, what about users whose browsers all still carry the old cert settings? I can't have everyone reset their hsts settings.

I think most likely this issue is only on your machine and not on others. Atleast, it works for me fine across multiple devices.

@jdaviescoates nope, just regular domains, not sure why but will just wait and see I guess

Since, we got so many support tickets about this already 🙂 I will paste what I said in the other thread.

Let's Encrypt have started using R3 as the intermediary cert - https://scotthelme.co.uk/lets-encrypts-new-root-and-intermediate-certificates/ . This cert has issuer text slightly different. Since the text has changed, Cloudron tries to renew the certs too early and this results in the above notification. The notification can be ignored since it's a false alarm, the certs and sites will be fine.

There are two ways to fix this:

Update to Cloudron 6 - you can go to Settings -> Check For Updates and then Update. It will give a notification that it is unstable. It's reasonably safe to update, the notification exists because we roll out updates very slowly to keep support manageable for us. Please expect some downtime (like 10 mins) since the update re-configures all the docker containers.

Alternately, you can make this one line change in your current Cloudron version - https://git.cloudron.io/cloudron/box/-/commit/3e62f1913ab05750a343c197c519d38bf17d5b3b . The file is /home/yellowtent/box/src/reverseproxy.js and then systemctl restart box.

@girish feeling lazy, will wait for the official update 🙂

So I'm pretty convinced the issue was the way I wrote the CAA records. I think my DNS provider didn't need the double-quotes in there and it caused issues. Reason I say that is because after introducing the CAA records, I suddenly had the certificate renewal errors.

Then when using a DNS check tool and I looked up CAA records for Google and Mozilla and more, none of them had the double-quote in there, but mine did. So I am sure that was the issue, as everything worked fine again after I removed the double-quotes.

I suspect the double-quotes was being taken literally as a string and so letsencrypt.org is not the same as "letsencrypt.org" in the DNS CAA record. I was able to later find the logs I had seen in the early morning which shows the following which confirms my conclusion: CAA record for <domain> prevents issuance.

So for anyone who comes across this later, make sure you're not using double-quotes I guess. haha.

@wu-lee do you know why it had failed to renew previously?

@andrewj720 Looks like DNS is not working on your server. You can also try host cloudron.io etc, I guess none of it working?

Can you check if your cloud firewall allows outbound port 53 UDP ? I think there was a post on this forum some time ago that someone had it blocked in AWS security group by mistake, for example.

@marcusquinn said in Lets Encrypt renewal time:

Without looking at that screen again, maybe it wasn't clear it should recommend using the root domain for that input?

I think many people start out just like you did and then move it to the main domain. We don't put the recommendation as such because I think it can be scary to throw your root domain and API credentials into a product you are just first trying out.

@marcusquinn said in Is there a way to set the LetsEncrypt email separately?:

So Superadmin's are Owners then? In that case I have about 20

Indeed! You can downgrade everyone to be an admin. The main difference between superadmin and admin are that superadmins is meant to be the person who has access to the server (and the one who set things up initially). Superadmin also manages the subscription and has acess to mail server logs. Admins don't have access to these two things.

Ideally, there is only one superadmin. We wanted to enforce this but migration from previous setups proved to be a bit problematic.

@murgero Thank you bro! I learned how to create and manage SSH keys via terminal today. I'm going to start learning how to do basic Linux Terminal Commands now. So when installing Cloudron, I should select Let's Encrypt - Wildcard and turn that to yes. Anything else that you recommend?

@Mightymoose There are two flavors of the WordPress app - managed and unmanaged (the former has blue icon and the latter has a grayish icon). Which one did you install? Can you try re-installing the app?

@girish This is an interesting observation. I was just looking to see if this was a real security threat or not, and I suppose it isn't but can offer a bit more privacy using the wildcard approach. Any particular reason why the Let's Encrypt wildcard support can't be done through the actual Cloudron wildcard DNS approach? Is there a way to support this? I'd really like to take advantage of a smaller DNS provider which has some great monitoring features included, but it isn't supported via any API by Cloudron yet, so if I go that route I can only use the Wildcard option, but those don't actually allow for the wildcard certificates.

Edit: Nevermind, I see why in the docs: "Let's Encrypt only allows obtaining wildcard certificates using DNS automation. Cloudron will default to obtaining wildcard certificates when using one of the programmatic DNS API providers."

So, it seems like giving the app a "relocation" by pressing the save button under the Location config tab & a quick Cloudflare proxy off-on, and then some time is the fix.

EDIT
So it is Cloudflare that is the problem and not Cloudron. Specifically their proxy
