Remote connection issue

Configuration

Hi,

I have a special question :slight_smile:

I have several HA systems running with nabu casa and duckdns.

I can reach them everywhere with my phone and any pc, exept at work.
When i try to log in at a pc at work i am able to go to nabu case and see my connection is ok, but when i click on the link the screen stays on “unable to connect to Home assitant” with the HA logo and retrying every 60 seconds, this is on all the systems.

A few months earlier it did work, so there either changed something in the IT department ( very big company so finding out is difficult) or some change in HA…
I don’t understand what could be blocking the connection?

Why are you using both?

Nabu Casa does not require duckDNS, and vice-versa.

In my case my employer’s firewall/proxy blocks dynamic DNS services like duckDNS, however it allows Nabu Casa.

You need to talk to your IT department.

Its rather trivial to block site X v. Site Y. These are just HTTS as far as your IT department is concerned. If they are using proxies on your outbound internet then they can also subscribe to packages that white / blacklist sites, entire IP ranges, residential IP service endpoints (cough) such as those owned by the large ISPs, etc.

Almost positive you’re getting filtered and

good luck building a valid business case to get the filter removed unless you have CxO in your title.

*edit : if you do have CxO in your title please don’t ask them to… They hate that.

I’m not using nabu casa and duckdns on the same instance of course.

I am sure it gets filtered, so there is nothing to do about it.
I just wanted to make sure i’m not overlooking something obvious.

Only this:
