Was this issue resolved for you?
Update - I tried signing in today and it worked - no error message. I didn't do anything differently - same user name and password. Who knows....
Your activation status is not complete. I have opened a ticket with our Customer Support team who will reach out to you via phone shortly.
Dear all customers who have same error like I did,
The solution is actually quite simple. When you signed up for Comcast / Xfinity Internet, Comcast site provided you a Comcast e-mail address. The front part of your Comcast e-mail address before the "@" sign is actually the Comcast / Xfinity UserID that you would use to log-in the Xfinity Home Mobile App. If you don't know such e-mail address / UserID or don't remember password, Comcast Tech Support / Customer Service Representatives can help you with that information and help reset the password to a temporary password for you to log-in to the Xfinity Home Mobile App. You can also log-in to Comcast.net with that UserID & password, and then change to the new password of your choice. Comcast Support Representative helped me w. both UserID & password. After that, I logged in the Mobile App successfully. So just give them a call.
I don't know why Comcast Support Representatives wouldn't go ahead providing this explanation.
I hope that everyone can see my reply on this forum to help solve the mystery.
Good luck, everyone!
Thanks for sharing this information. However, this is just one of many reasons that cause a 43500 which is why I respond to each person.
It could also be that the account activation hasn't been completed, a person is using the wrong version app (we also have a Comcast Labs app), or several others.
If resetting your password to the user account for the Comcast email address you signed up with doesn't work for you, please be aware there are other reasons for a 43500 on login.
I am getting the same error message 43500 in my iphone device. i also check the web portal all i see is the ad page to have xfinity home.
How can i remedy this problem. most of the time i am always out and i want to see my family it they are home.
You are using the wrong app--our Comcast Labs app which is used for testing. Please download the black and red app. You should be able to log in after you download this app.
My problem now is that, even my touchscreen on the security part where i can enter my code is not working anymore. I tried rebooting it. then my portal webbrowser is not working also.
It shows on the touchscreen most of the time network lost. then i restart my router and modem desinated with home security. same result.
i also check connectivity, the cellular data has an error also
Your account is still in the activation status and needs a rep to complete the process before you can start using these features in a stable manner. A ticket is open and in progress for your issue. I will follow up with today.
I don't see you registered as an Xfinity Home customer. I am opening a ticket and a Customer Support rep will be in contact with you soon.
i am geting the same error message as everyone else. I am using my primary comcast ID. This ID has worked in the past to login to the app. I logged in with the same id to the xinfity website and it worked fine. I was able to access my home security system without issues.
The app used to work great. Now it is totally useless. Nothing has changed on my end and i log into xfinity just fine.
please help! I am paying a lot of money for this home security and i cannot even use it properly
Same issue here. Also can not login online, all I get is the advertisement page. It would be nice to know if my system is armed. I have had nothing but problem after problem with Comcast since we have moved and I'm ready to cancel all of my services.
This solution was able to fix my problem. Can I recommend that you change the name of the "labs" app to something that will let the user know it is not the correct app for the home security system?
