Hass.io Add-On: letsdnsocloud - Custom Domain SSL & DDNS

Hi @hars, I’ve tried both internal and external. Same result. Fairly sure the issue is with the generation of the ssl rather than routing. Could however be wrong!

I think there may have been an issue with the underlying script the add-on calls (Dehydrated).

I updated the config to use the latest version of that script. Try deleting the add-on and adding it again and it should work.

I updated my hassio to the latest version, deleted the certs and add-on and reinstalled and everything worked fine.

What you should see in the log:

Updated your.domain.name with IP: **.**.**.**

@hars, still the same unfortunate. I:

Uninstalled the add-on
Restarted Hass just to be safe
Re-installed add-on
Set/Saved config options
Started add-on

Same error:

Updated sub.domain.net with IP: myipaddress
/usr/bin/dehydrated: line 1: 404:: command not found

fyi as might be relevant, I’m running hass (170) on a synology disk-station, letsdnsocloud is showing version 1.1. Not sure if this is as expected, my /data/workdir/config is empty.

The Cloudflare component is working as expected with the A record being updated.


Ah, most likely yes.

Does /bin/bash exist?

What is the output of “echo $SHELL” ?

My knowledge of Synology is next to nothing but it looks like perhaps it doesn’t use bash if you’re getting a commend not found error.

Yes it exists, however is empty:

Sorry I really don’t have the chops to try and help you fix this. I’m pretty new to Hassio and have no experience with Synology.

Have you read through this thread?

It looks like the Synology install is pretty tricky and takes some fiddling around to get it working.

Hassio under Synology should behave the same as under other environments. It is “virtualized” via docker so addons should not be affected of underlying system.

Hey @hars, I’m trying to get this installed on hassio supervisor 181, but when I try and run the install, I get the below stack trace

Similar issue below - do you have enough space on whatever drive you’re using? Another common issue to hassio installs that could cause that problem would be a corrupt sd card.

Thanks for the quick response… I’m running on an SSD w/ Gbs free… BUT what is super odd is this morning when I checked, it was suddenly installed… I’m wondering if maybe there was some issue w/ hass.io caching the response… I tried with a few different browsers, so I doubt it was a browser cache issue. :confused:

Thanks for this addon! Exactly what I needed. However, I followed the instructions and get the following error:

2019-08-25 19:21:51 ERROR (MainThread) [homeassistant.core] Error doing job: SSL handshake failed
Traceback (most recent call last):
  File "uvloop/sslproto.pyx", line 500, in uvloop.loop.SSLProtocol._on_handshake_complete

  File "/usr/local/lib/python3.7/ssl.py", line 774, in do_handshake
ssl.SSLError: [SSL: HTTP_REQUEST] http request (_ssl.c:1076)

My configuration.yaml looks like this (certain bits redacted):

  base_url: https://home.example.info
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem
  ip_ban_enabled: true
  login_attempts_threshold: 5

I guess the only thing I could think of is that the ssl directory is created at the same level as the config directory i.e. hass.io -> config and also hass.io -> ssl. Is that correct? (I’m running Virtualbox)

This error is in multiple add-ons and super common, check it out:

Give this a shot and see how you go:

Thanks, well in fact it was working all along! I didn’t realise that my internal IP would not resolve after this addon was enabled, so I thought my hass instance just wasn’t working, as it wasn’t connecting to my local internal IP (http://192.168.1.x:8123) - switching to the new URL (https://subdomain.domain.info) works just fine (both internally and externally). Still getting that error, but I can live with that until a fix is found.

My only question I guess is, should the internal local IP still work? Not a big deal, but would be nice to know if I’ve configured it correctly.

Oh, yeah - it’ll still work just not on the internal IP.

Internal IP won’t work if you enable https so you’re all good.

fantastic work thank you!

I can’t get it working. I only can enter in the same LAN, only via IP if I try to enter remotely.

jq: error (at <stdin>:0): Cannot iterate over null (null)

I am also interested in leveraging the Bitwarden add-in. Will this add-in support SSL for both Hassio AND additional add-ins one might add? Figured I would post here to check before I jump into the code…

First off, thanks for the add-on @hars.

I just came back to my hassio install after some time to find that letsdnsocloud is erroring out complaining about nonces. It looks like the Dehydrated version needs to be bumped based on these bug threads: https://github.com/lukas2511/dehydrated/issues/684

It seems that forcing a rebuild/rerunning the add-on repeatedly got it to randomly work (which reports on those threads suggested would work as well) but getting upstream Dehydrated fixes to get around this properly probably aren’t a bad idea.


already running the latest release: https://github.com/PhrantiK/hassio-addons/blob/36e9f0e5ecc633b008654ee6cea1383d45bc2dd6/letsdnsocloud/build.json

What is the exact error message you’re getting?

I haven’t touched my Hassio install in months as it “just works”. If I find the time I’ll update and see if I get the error messages.
