Issue with app connecting on launch - reasonably sure it's related to enabling mtls

[stever29]

Home Assistant Android app version(s): 2025.11.4-full

Android version(s): 16 / OneUI 8

Device model(s): Samsung S25 Ultra

Home Assistant version: 2025.11.3

Last working Home Assistant release (if known): N/A

Description of problem, include YAML if issue is related to notifications:
Since enabling mtls, the app regularly says 'Unable to connect to Home assistant'. Pressing retry between 1-3 times always results in a successful load. This happens on a very good network connection. It happens extremely regularly, but will only happen if you haven't used the app immediately beforehand (i.e. something like a session has timed out or the app has gone to sleep).

(I just want to say I super appreciate the work that went into enabling mtls, even with this issue it's amazing we have this on android.. thanks!)

Logs were massive and I'm not sure which bit was relevant so attached:
