Connectivity Issues - duckdns

roostlick · June 29, 2018, 3:52pm

Hi Guys

Suddenly started having issues today, my duckdns (inc letsencrypt) setup has been working fine since last September.

All of a sudden today I’m unable to connect to my HA on the duckdns when on the internal network. Was advised it could be a nat loopback issue but nothing has changed on my modem or router, no firmware updates etc.

For some reason now I can access it via internal IP address on my wired desktop PC, but if I try and connect on my iPhone, the only way I can get it to work is to disable WiFi and connect via the duckdns address but over 4G.

I’ve looked in the log files and can see the below:

ssl.SSLError: [SSL: HTTP_REQUEST] http request (_ssl.c:777)
2018-06-29 16:42:56 ERROR (MainThread) [homeassistant.core] Error doing job: <uvloop.loop.SSLProtocol object at 0x731d9cd0>: SSL handshake failed

I’m on 0.72.1 and there’s no errors I can see in the DuckDNS add-on log.

Any help would be massively appreciated, thanks!

GrahamS · June 29, 2018, 11:32pm

I started to get these errors too when I updated to 0.72.0
These errors do not seem functionality. They occur with “Task was destroyed but it is pending!”
I can still access hassio from WiFi or 4G using the same DuckDNS URL.
To get this working I had to install DNSmasq add-on since I don’t have NAT loopback on my router.

roostlick · June 30, 2018, 12:17pm

And without me doing anything…it’s started working again as it should do this morning…confused haha!

I’m also getting these errors, it doesn’t seem to effect access to home assistant but it’s constantly spamming my log.

Does anyone have a solution?

genik · July 3, 2018, 5:38pm

Hi everyone!

I actually have the same problem - no access to HomeAssist through “duckdns”. Though from local net there is the access. Here is the text i receive in module DuckDNS:
" end of string encountered while processing type of subject name element #1
problems making Certificate Request".
The access through DuckDNS has worked successfully for a year. The problem appeared a few days ago.

Did anyone find the solution? Any piece of advise?

Thanks.

S401 · July 3, 2018, 8:24pm

I’ve got the same errors as you.
I don’t have access through duckdns and the only way i can connect is through my local network.

I hope there is a solution for this problem!

roostlick · July 3, 2018, 11:29pm

After working fine for another few days, it has stopped working again today.

Getting these errors in the log files whenever I try and access via duckdns:

2018-07-04 00:24:57 ERROR (MainThread) [homeassistant.core] Error doing job: <uvloop.loop.SSLProtocol object at 0x7396a6f0>: SSL error errno:1 reason: HTTP_REQUEST

Tried uninstalling and re-installing the duckdns add-on, but from what I can tell in the log it’s all setup and working perfectly. But still no access via duckdns address internally, but it does work if I switch wifi off on my phone and use 4G. Does everybody elses duckdns work when accessing outside of your network??

I’m using cludflare as ssl. But I’m also getting

My problem was that my certificate expired. The problem was that i used both the Let’s Encrypt and the DuckDNS add-on. I deinstalled both and only reinstalled the DuckDNS add-on. After i changed “accept_terms”: from false to true, my certificated got renewed.

But that did not fixed my errors in the logs. After enabling the logger component i saw in the logs that the Sabnzb debug info was the error. So i added Sabnzb at the Discovery Ignore list, after a restart the errors didn’t appear any more in the logs.

Got the same issue. Not able to access HA at all. This is a brand new installation of the duckdns add-on.

Having the same error, started a week or two ago:

Error doing job: SSL error errno:1 reason: UNKNOWN_PROTOCOL

JoniR · July 11, 2018, 12:00pm

I don’t use HASS.io, but I faced same issue with normal docker installation at version 0.73.1.
Home Assistant stop responding after while. If I restart Home Assistant everything will work and can be accessible via DuckDNS uri.
Log give me these:

Mine has been working fine for about a week (it just started working without me doing anything), an again this morning it has stopped again, perfectly on 7am as well according to the logs:

Torbenan · July 16, 2018, 5:04am

I see the same issue. Did you solved it?

skymoo · July 16, 2018, 6:57am

Been seeing this as well, all of a sudden it’ll just stop loading. I get the password prompt but then it fails to connect. If I load on the local ip address then I can load the interface if I add exceptions for the SSL cert. The only thing I’ve found that gets me back up and running is to do a completely fresh install and then restore from a backup from before the problem started happening.

However I’ve done three reinstalls tonight and so far each one has resulted in the same problem when restoring from the backup.

skymoo · July 16, 2018, 7:00am

Also I sometimes get an error from the browser of the following form:

Corrupted Content Error

The site at https://hostname:port/ has experienced a network protocol violation that cannot be repaired.

roostlick · July 16, 2018, 10:04am

I’ve got no idea on this one. Mine has had the issues about 3 or 4 times, but it will seemingly fix itself and work for days at a time with no problem whatsoever.

Bobby_Nobble · July 16, 2018, 6:20pm

Mine’s been 100% reliable for many months and has literally just stopped working, no errors in the log. Might have been with the 73.1 update but can’t be sure.

Bakko65 · July 16, 2018, 8:11pm

same here, did a full restore of HA without DuckDNS, errors gone.
After installing DuckDNS and get the new cetificate the errors are back.
It’s working fine from outside but I don’t like the errors.

Error doing job: SSL error errno:1 reason: HTTP_REQUEST
Error doing job: SSL handshake failed
Error doing job: Task was destroyed but it is pending!

The log is full with those errors
