And how can I check that?
You can check if the homey is on the same network if you are on the same WIFI access point. Although it should work if you are not, but Iāve had some issues in the past too with thisā¦sometimes it works, and sometimes it doesnāt. Itās easy to test.
Did you initially use the same Amazon server (Europe), before you got this issue? (it seems to bind to the server where the account was created first, even if you migrate later to USA, for example, to be able to test features that are only available for USA). Although Iām probably the only one that would setup something like this 
Ok so Iām on the same network. All my domotics is connected on the same access point.
Iām on the european server since beginning, on amazon.fr
Iāve tried with the homey app on my android phone and in the web homey page and itās not working on both 
Unfortunately, Iām not at home at the moment, so I canāt make a quick test setup to see if I can reproduce your issue right now. did you already try to restart the Homey Alexa app as well? then try to reconnect again.
Yes Iāve tried several time to restart homey and the app.
Iāve also tried to uninstal/reinstall the app and even tried the experimental app v5.4.3.
Iām currently running 5.3.14, and have no issues at the moment
This error happens when amazon is having issues (incredibly rare, not something I have personally seen) or if the mobile and homey are on different networks.
Though I suspect if there is a VPN or some sort of proxy already in place it would cause a lot of issues for the login as well.
@Renaud_Climent = I received a diagnostic yesterday - but there wasnt enough information to determine who it was for ā¦ just a really unhelpful āConnection Impossibleā in the description. - Not sure if this is you or not.
Hi, I am sorry to say I have the same problem.
I am on the same router and WiFi net as my HomeyPro2023 and have tried with PC, iPad and iPhone and also both American and European server. No luck.
A very strange observation is that when I should type in my SMS MFA code, the numbers cantāt be typed as they ādisappearā. I circumvented that by pasting in and press Enter.
I have been trying now several times a day for over a week.
I am trying to add an Echo Show 5 3gen and an Echo dot 5th gen.
Regards
Tom
When i go back to work iāll try to reinitialise all my system (wifi / alexa / hjomey) and iāll let you know.
Sorry when you say you have the same problem, it asks for the MFA the shows a error page?
Yes after the acceptance of the MFA Code I get the screen from Amazon with a picture of an animal and message saying Sorry something went wrong
Tom
Even with the reinitialisation of homey + my WIFI router + all my alexa devices = same problemā¦
Error page when i enter the MFA code
Sorry,
I did have a look into this error, but I wasnāt aware that it was happening AFTER the MFA request - meaning it was working but it was actually the call back failing.
I dont have any more time at the moment to look into this again, perhaps subscribe to this thread and if I am able to get the information required to investigate this issue (and some more time) I will do.
Going forward, can everyone please make sure you supply me with all the information that you have - images, videos, descriptions of what you doing etc, what devices what version of homey what version of the app your network etc etc. and it is in English. . Going forward I am going to be ignoring all posts for help which donāt have all available information - as it just burns through the little spare time I have.
Seems like you both have issues with MFA - I wonder what happens if you disable MFA and try and connect. ā Perhaps something for you to try.
The MFA authentification is only active on Homey.
I have never had an MFA anywhere other than homey to connect to amazon. Itās the first time I see that kind of authentification for amazon.
Hi again,
I have done several tests and yes the problem is related to MFA.
- I created a new Amazon account without phone number or MFA. I was successfully able to link the Homey Alexa app to this Amazon account without any MFA question.
But this is an empty account without my Echo devices so I am not able to use it.
- I enabled MFA on my normal Amazon account and then disabled it again. I also deleted the telephone number on the Amazon account.
I was able to log into Amazon without any MFA questions.
- I tried to log into the Alexa app with my normal Amazon account (the one without MFA) both on the US server and on the Europe server.
In both cases I still receive an MFA question from Amazon even though I do not have any MFA any longer. It seems to remember it somehow. Amazon sends the code to my email since I have deleted my phone number.
This is the login screen I get. Please note the IP address, doesnāt this look strange?
Image one
After logging in, I get this screen in German. Also strange.
Image two
After entering the MFA code I end up at this screen.
Image three
I have been using Google Chrome on my PC to perform these tests.
I have Homey Pro (Early 2023) with version 10.0.5
I am using Amazon Alexa app version 5.3.14
Anything else I havenāt thought off?
Regards
Tom

Is anyone using (or has used) MFA successfully?
I am not sure why it wouldnāt work - but it might just be one of those things.
I donāt have any plans to turn on MFA on my own account - because if itās not possible to resolve I wouldnāt be able to work on the app againā¦
Iāll have a think, but letās see if the community has had it working in the past
@Jamie is this something that can be resolved in the app? (Iām pretty sure this didnāt happen in the past, although that was also on my Homey 2019)
I am using the app with mfa since day one.
I didnāt have to reauth recently so cant confirm if it broke
