Cant connect via local network but dyndns works !?!

Installation Home Assistant OS
1

Here is a weird one and just wondering if anyone has some suggestions to isolate what is causing it.

my hassio.local stopped responding (Even via direct ip) but the .duckdns.org continues to work(!) - no idea how that is even possible :wink:

backstory is that I installed hass.io on new raspberry 2 days ago and been tinkering on/off and all been good. last night I setup some appdeamon automation and its been running fine for almost 24hrs.

Then I noticed some lights turning on/off that wasnā€™t as I expected and then wanted to look at logs - and then couldnā€™t reach homeassistant via local ip/names.

weirdly enough duckdns works.

while writing this I rebooted hass.io via the system menu but after restart same thing - duckdns works but local does not.

Iā€™m very puzzled! any ideas ?

Is it working with the local IP of your HA device?

Edit: Sorry didnt read correctly. Ignor me please

its very weird - Iā€™m suspecting my netgear orbi network is misbehaving - its telling me iā€™m not on an orbi network but no way I canā€™t be that as Iā€™m able to post here :wink:

sounds like your router doesnā€™t support loopback

interesting, im fighting some related issues with duckdns, but not quite what your dealing with.

Also have an Orbi.

Do you have port forwarding setup? which ports are you using?

trying to read through the info online, it appears that once its all setup that you are supposed to use the same URL internally as externally? not sure im reading that right. thats from: https://www.home-assistant.io/docs/ecosystem/certificates/lets_encrypt/ which obviously doesnt apply if you are doing the duckdns add on setup, but was referencing that to see if i could find a hint.

anyway, are you port forwarding?

Yes Port forwarding on my router to the ip of Hassio - which for reasons I canā€™t figure out is NOT reachable from my laptop.

What I can do though is to login into my nAS and then I can ping and ssh to Hassio just fine. Itā€™s as if my laptop been isolated of from talking to hassio. So weird.

7

Can you ping by IP address, hassio.local or your dyndns address from your laptop?

8

No,hassio.local worked fine the other day and also works from other machines in the network (nAS and phones).

Itā€™s weird.

9

I can ping the duckdns but not local ip or DNS name.

10

Can you please copy and paste the output of those ping commands (including the commands themselves.)

11

simply just a bunch of ā€œRequest timeout for icmp_seq nā€.

Now tonight access is restored - iā€™m starting to think my orbi routers starting to struggle with my number of devices or somethingā€¦

12

right, so not a home assistant problem at all :slight_smile:

13

No, but initially I thought it was as it only happens for the hassio device. Not everything else :slight_smile:
