hi,
I got following error during connection to the Somfy Connexoon Box:
Status: OFFLINE - COMMUNICATION_ERROR Authentication challenge
The app is still working but I cannot login by using the webinterface.

Hi, I have the same problem since the last Tahoma update and I use the openHAB 2.5.7 release build. After I also got the error “Too many request error”, I now have the error “somfytahoma:bridge:xxxxxxx’ changed from ONLINE to OFFLINE (COMMUNICATION_ERROR): Cannot get login cookie”. Funnily enough, this error no longer appears when I log in to Tahomalink via webinterface of a normal browser (not the TaHoma app). After a while, however, the error reappears in OpenHAB. I don’t know well technically, but does this have to do with any login sessions that may be associated with my Internet IP address, as I only see the IP address as the only commonality between the webinterface and openHAB? I can’t explain it any other way.
Hi , i’ve got the same issue with 2.5.7 (unfortunately I missed to check immediately after update to confirm connection with the update)
Have you solved the reported problem in last 2 weeks?
I set up a fresh OH2 and it was there as I made a mistake. It can be resolved with clearing cache and reboot (several times)
After an update and several restarts it worked.
Hello, I had an issue today when updating to openhab 2.5.8-1
See here Items lost + error 500 after update to openHAB 2.5.8-1 (Release Build) ...backup not working :-(.
The guilty one was the link between the RSSI thing and item. Everytime I link the thing and item, All Paper UI items are not visible. Here is the error in openhab.log
2020-09-13 21:55:38.491 [ERROR] [ersey.server.ServerRuntime$Responder] - An I/O error has occurred while writing a response message entity to the container output stream.
Also, when I try to set a location for my Roller Shutter Things, via PaperUI, it’s not working.
I have Error 500 when saving the thing, and the location is not saved.
It’s working for the scenario (Somfy Action Group)
If you definde your things in text configs, ou cannot change t in PaperUI.
But you can set the location in things file as well
"your label" @ "your location" [config options]
Hi all,
I have had OH2 operational for a year or so now. I have just recently added a Somfy Connexoon box (in Australia) along with the Somfy Binding v2.5.9 however I am not able to authenticate with the following error displayed in the Paper UI when I enter my credentials for the iPhone app:
Status: OFFLINE - COMMUNICATION_ERROR Authentication challenge
I have everything operational with my Somfy Connexoon app on my iPhone. I am told by Somfy Australia that there is no online account to log in through the web so I am at a loss as to why I am getting this error. I do not have a Tahoma login but I’m not sure if I need one.
Sorry if this has been answered already however I couldnt find any answers when searching this thread.
Thank you
Anthony
Sounds like the same problem I’ve had not long ago. When I set logging to debug I got the error " skipping login due to to many requests" if this is the same for you, I got my problem resolved by:
- Uninstalled Tahoma binding
- Rebooted OH
- Cleared OH Cache
- Rebooted OH
-(re)Installed Tahoma binding.
Hope this works for you.
Btw. If you have a conexxoon you don’t get a tahoma login. Your conexxoon however logs in at tahoma cloud. But you are not able to interact with it yourself via a browser. Only Tahoma users have this privilege.
Hi Marty,
Thank you very much for your response.
I tried the steps you outlined in your response but unfortunately it didnt work.
Just to confirm, it is the Somfy Tahoma Bridge Thing I install, not the Somfy Tahoma Gateway?
Does anyone have any other suggestions?
Regards
Anthony
I’m experiencing the same, also with a Connexoon.
This has worked fine since late 2019 but only started giving issues after the most recent Connexoon firmware update.
I also can’t seem to log into the TaHoma website with my account even after resetting password, I was sure the password was correct in the first place though.
Maybe some changes were made from Somfy’s side?

I disabled the binding for a day and just enabled it again and now it can log in again without issues.
Not sure if this is coincidence or not but happy it works again 
So i ran into the exact problem yesterday. OH stopped being able to control my Somfy IO devices. Checked Gateway status, being in an error state with error : “Authentication Challenge” .
Disabled the Gateway thing thru PaperUI Last night and enabled it this morning. I’m Up and running again. Maybe a ban on logging in thru the binding for a period of time? I haven;t changed the refresh rates on the binding so i shouldn’t be hammering the API?
Same problem here with paperui…and I have set my things not in texfiles…
PaperUI is full of bugs, try Habmin instead, the location can be set even if PaperUI reports internal server error.

Hi all,
Unfortunately the Disabling over night and re-enabling did not work. I have never had this Binding operational so I am wondering whether I am doing something more fundamentally incorrect. I have followed the Binding instructions on the OpenHAB website. Is there a need to point to the Conexxoon bridge IP in any way?
Here is the error:
2020-10-08 09:23:19.893 [hingStatusInfoChangedEvent] - ‘somfytahoma:bridge:1750181e317’ changed from UNINITIALIZED (DISABLED) to INITIALIZING
2020-10-08 09:23:21.395 [hingStatusInfoChangedEvent] - ‘somfytahoma:bridge:1750181e317’ changed from INITIALIZING to OFFLINE (COMMUNICATION_ERROR): Authentication challenge
Any assistance would be greatly appreciated.
Thank you again
Anthony
Hi,
first of all you need to be sure, that you can log in with your credentials to http://tahomalink.com portal.
Some Connexoon users have already reported some problems. If you can’t login, the binding simply won’t work.
Regards,
Ondrej
Hi Ondrej,
As a Somfy Connexxoon user, you are not give a tahoma link account for the portal.
I am perplexed as to how some Connexoon users can set this up and others cant.
Any advce would be welcome?
Regards
Anthony
In case it helps anyone else, I gave up on using the Connexoon and built an Arduino MQTT/RTS bridge instead: https://github.com/richardbounds/Arduino_SomfyRTS
