Connection problem with HA app an Web

Hello everybody, I have a problem to access a Home Assistant App and the Web page. From the app I received a error message - 6 but I have CLI only access. The IP address it’s the same in my router and the CLI from raspberry pi 4. Somebody else has been that problem?

Are you using AMP Alexa Media Player by chance? Then you need to read and follow the steps outlined here: PSA: Alexa Media Player v4.13.3 breaks all versions of Home Assistant - #2

I have never been able to add alexa media player to my Home Assistant.

So we are back to the standard issue setup/networking. Okay, what is the network subnet setup for the location? What did you setup on the HA for network?

Sorry, I don’t understand :sweat_smile:

Actually you lost me when you said you were trying to add the Alexa Media Player. It was a simple question (yes/no)
If yes then you have to do some work to fix the Alexa Media player which is crashing HA due to a memory leak issue. (I provided a link that you need to read and understand what is happening and what to do).
It was not for you to add it if you don’t have it already installed.
If you do not have it installed then it is a network setup issue that is keeping you from seeing the HA
