I think the important line is this:
Caused by: java.io.FileNotFoundException: /usr/lib/libnss3.so

The file /usr/lib/libnss3.so is needed by Java to support SSL and this file is not present on your OpenWRT system.

What device are you using to run OpenWRT and what version of OpenWRT are you running?

Thank you very much for your answer. I am using a soft router running OpenWrt, with a CPU of ARMv8 architecture RK3568, and the OpenWrt version is 23.10. How should I handle this SSL issue? Is my Java version compatible?

[simoncn]

I will try to set up an OpenWrt image for my Raspberry Pi 4 to confirm what has caused this problem.

In the interim, you should be able to get MinimServer running by disabling automatic updates. To do this, create a file named minimserver.defaults in the minimserver/data directory. This file should contain the following line:

.autoUpdate = false

After doing this, start MinimServer and it should run without producing this error.

Edit: I was able to start OpenWrt and confirm that it doesn't contain the provider library needed to support SSL. This causes Java to throw an error. MinimServer should detect this error and fall back to a non-SSL connection. Changing the Java version wouldn't make any difference. When this MinimServer fix is available, I will post back here with details of how to install the fix on OpenWrt.

Using this method results in another exception as follows:

MinimServer error: now stopped, use 'restart' or 'exit'

[simoncn]

I have investigated why you are getting this error. The file libohNet.so (needed by MinimServer for UPnP support) is compiled with glibc and needs ld-linux-aarch64.so.1. OpenWrt doesn't include this file but instead includes the file ld-musl-aarch64.so.1.

To solve this problem, you would need to build OpenWrt with glibc instead of musl. There are instructions for doing this on this page. I haven't tried this and I can't be sure that it would be enough to enable MinimServer to run.

Reconstructing OpenWrt from scratch is quite difficult for me, and I have already set up a variety of plugins. Are there any alternative solutions? Thank you.

[simoncn]

I have done some web searching and I haven't been able to find any other solution.

Thank you very much for your answer. It seems that I can only give up using minimserver as the server. It’s so miserable.

[simoncn]

You could use a Raspberry Pi to run MinimServer. In the UK, the RPi4 2GB model can be purchased for GBP 43.
