Version Information

App Version: 1.27.6
Android Version: Android 11

[midwesternrodent]

I saw the same thing on Android 14 with Syncthing version 1.28.0.

I ran into it because for some reason my syncthing died on android. Unfortunately, I didn't grab any logs before I started troubleshooting but I have other family members using it and if they run into issues I'll pull from their devices and open a new issue on that in particular.

What fixed this for me was completely uninstalling syncthing, restarting my phone, and re-installing it. I installed via obtanium of course, but I imagine f-droid should be the same thing. If you've already done that, could you try the direct APK download and see if that works?

It seems that there is something being held on to by syncthing after clearing the storage which is what the config error seems to be complaining about. I also forgot to grab that from my end, but my error when on after the "..." you shared and mentioned that a key had already been created so it would not override, which is what clued me in to do a full re-install of Syncthing with a power-off in the middle.

Tried that, did not work.

Did not work either, exactly same logs, abruptly ending at "Generating ECDSA key", nothing about the key that it would not override.
