Title. Trying to diagnose an issue with my modlist and the Crash Assistant UI won't upload things. I get this message:
Failed to upload file "crash-reports/crash-2025-05-19_13.00.28-client.txt": java.util.concurrent.ExecutionException: javax.net.ssl.SSLException: Received fatal alert: bad_record_mac
I'm using Prismlauncher on Fedora Linux 41. Oddly enough, I can sometimes click Upload and copy link on individual buttons and they work sometimes, which is how I was able to get the crash_assistant_app.log here. Only the crash assistant log button worked this time, but I've had it such that all of them worked except for latest.log and debug.log, for example. Let me know if I need to provide any other info. I also usually use a system-wide VPN but I tested with the VPN both on and off.

Due to the upcoming 1.16.5 backport — and consequently a Java 8 backport — we will be removing the McLogs Java API (which requires Java 11+) and replacing it with our own implementation.

This is not an issue with Crash Assistant itself. It's most likely a connection error, but could potentially be a bug in the McLogs Java API.

If you're experiencing connection errors, you can drag and drop files directly from the GUI to any location, or drag all logs from the “Available log files:” label.

This is a rare issue and has only been seen a couple of times out of 7 million downloads.

Since the McLogs API will soon no longer be part of the mod, I’m closing this.
If the issue occurs again after the 1.9.0 update, feel free to reopen it.
