Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/1448

Steps to reproduce:

Open ntfy android app. Subscribed topics are shown
The first topic shows three notifications, which is correct. Tap on that topic to view notifications. The app crashes.
Reopen the app and try again. Same things happen. Android has a pop-up that says the app keeps crashing.

Clicking on a topic with no notifications doesn't crash the app.

The ntfy server is locally-hosted, running in a docker container in a different network than the phone. The connection is over tailscale.

I can connect normally to the ntfy server via tailscale on the same device using a web browser.

This has been working fine since I started using it about four monghs ago. This problem just started within the last day or two.

I tried reinstalling the app from F-droid. Also updated the docker images and restarted the server. Didn't help.

Below is a log around the time where a crash happened, which was when I tapped to view a topic at 12:04:00.

`This is a log of the ntfy Android app. The log shows up to 1,000 entries.
Server URLs (aside from ntfy.sh) and topics have been replaced with fruits 🍌🥝🍋🥥🥑🍊🍎🍑.

Originally created by @karlkec on GitHub (Sep 23, 2025). Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/1448 Steps to reproduce: 1. Open ntfy android app. Subscribed topics are shown 2. The first topic shows three notifications, which is correct. Tap on that topic to view notifications. The app crashes. 3. Reopen the app and try again. Same things happen. Android has a pop-up that says the app keeps crashing. Clicking on a topic with no notifications doesn't crash the app. The ntfy server is locally-hosted, running in a docker container in a different network than the phone. The connection is over tailscale. I can connect normally to the ntfy server via tailscale on the same device using a web browser. This has been working fine since I started using it about four monghs ago. This problem just started within the last day or two. I tried reinstalling the app from F-droid. Also updated the docker images and restarted the server. Didn't help.
