Hostname Certificate Mismatch on Android

[serene spruce]

My issue is similar to the one in "https://discord.com/channels/330944238910963714/1285569621562363966" but i am using cloudflare tunnels and i am able to connect to it on my browser and on the ios ha app but not on my android, everything works perfectly fine on the browser version on my phone and also when i use the internal ip address

hostname mismatch sounds like a local dns issue

what could be causing that?

[sand snow]

that i am not sure but its comign from the network

the app seds the request to the URL and we get an error message

these error messages can only be solved server side

it really depends on your own setup

but it works on the browser on my phone

this page offers some tips and guidance https://companion.home-assistant.io/docs/troubleshooting/networking

browser on the phone does not use APIs that the app uses

the apps use all communication methods from the server

i did look at this and the only thing i found that could maybe solve my issue was the tls client auth section and i installed the cloudflare tunnel cert (i think) and it didnt seem to fix it

[sand snow]

have you already tried restarting things like the host HA is on and your network etc... that sometimes fixes things for users

its on the raspberry pi and ive restared both the pi and my network a couple of times

The URL the app is configured for is the same as the URL you've used in the browser on the same device? And you're not seeing a security error when hitting https://yourdomain.com on your device?

Are you able to inspect the certificate

[serene spruce]

nope, it works on the browser on my phone, laptop, ipad and the ipad application, the only issue is in the phone application

[serene spruce]

on my laptop browser, yes

The URL the app is configured for is the same as the URL you've used in the browser on the same device?
Is the answer to this "yes"?

[serene spruce]

yes

Is the device running a modern version of Android?

[serene spruce]

yes

android 14

[serene spruce]

i tried it with a different android device and it had the same issue

[serene spruce]

this might be right, i asked one of my friends to connect to it and they were able to connect to it without a problem, maybe ill mess around with my network settings to find a fix

[sand snow]

check the DNS bits in the link above they may be of help

[serene spruce]

how do i do that?

i did a network reset on my old phone and that did not seem to fix it
