"Resource not available" error message fixed in MinimServer update 248 - simoncn - 12-03-2024 17:10

There have been a few recent reports of a message appearing on the MinimServer configuration web page saying "Resource not available: https://minimworld.com/updates/minimserver-2.2.jmupd". When this happens, it is also not possible to activate or deactivate the license.

This problem is caused by an SSL certificate error. It started about 3 weeks ago when the hosting provider for the MinimServer updates and license server made a change to the SSL server certificate for the minimworld.com domain. This change didn't affect most MinimServer installations or the minimworld.com website but it did cause problems with some MinimServer installations running on older levels of Java that weren't able to validate the new SSL certificate. Specifically, the problem affects Synology devices that are running DSM 6.x, DSM 5.x or DSM 4.x and have an Intel or PowerPC processor. It also affects QNAP models TS-109, TS-209 and TS-409.

An issue like this would usually be fixed by releasing a MinimServer update for automatic installation and this fix is now available as MinimServer update 248. The problem in this case is that the devices affected are unable to install updates because this requires an SSL connection to the updates server, so an alternative method of installing this update is needed. The release notes for this update include instructions for how to work around this problem and install the update on affected devices (see this section).

Please post here with any questions about this problem or the solution.

After a restart today my log shows:
java.lang.NoClassDefFoundError: Could not initialize class sun.security.ssl.SignatureScheme
and a series of subsidiary entries.

I am on Java 1.8.0 (build 401.b10) on a Windows 10 PC.

So far I have not connected this with any problem in Minim... functions.

Please post full details of this (including the full text of all subsidiary entries) so that I can investigate. Many thanks.

Log attached. If you need me to change the log level, restart Minimserver, and give you the log again, let me know.

Thanks for this. It looks like the error happened when you were trying to play a network stream (internet radio station) that has a URL with an https: prefix. Do you know what network stream this was?

It was one of the stations in my .m3u8 list. I didn't want to post it on the forum, so I used your License Contact mail form.

Thanks for sending this list. I tried the two https streams you marked as not playing with MinimStreamer but these have a different problem (not SSL). I will try the other https streams to see if any of them shows the SSL error.


RE: "Resource not available" error message fixed in MinimServer update 248 - simoncn - 13-03-2024 22:42

I tried playing all the streams (https and http) but I didn't see the SSL error from any of them. I did see it once in the log just before a rescan of the playlist but I was not able to associate it with any specific stream or make it happen again.

It gets worse, much worse. A Windows 10 update was on deck, so I restarted the PC and let it happen.
Normally after an update, I launch Minimserver by clicking on a shortcut which goes ot
"C:\Program Files\MinimServer\lib\mserver.jar"
But now Minimserver does not start. The click simply takes me to a .jar file. (screenshot attached) The same thing happens if I try to start Minimserver from Windows Start.
After this Windows update, Microsoft's Files program is intrusive in place of Explorer. I hadn't noticed it previously. The attached screenshot is cropped from a Files window.

The minimserver log shows:

These log messages don't seem to be related to the problem with starting MinimServer. The messages just indicate that MinimServer was closed while some activity was in progress and you don't need to be concerned about them.

To fix the startup problem, try running the Jarfix program. This repairs the broken association between .jar files and the Java runtime that was caused by the Windows update.
