Not able to print or preview new uploaded files

Topsurfer

Hi,
after few weeks I try to upload and print an older stl-file, but after uploading there is now "Print"-icon (or option) in the web view, and after the "rendering" -info (3 minutes ...) the preview is still empty. Only the "delete" icon is there.

See 01.stl:

The files (converted 2 month ago and successfully used with this repetier-Server!) looks correct, because other program can read the files etc.

I still has try the hint to stop the server and delete the workdispatcher.sql  fileand restart, but nothing changed.

The only thing in the last week was a change in home network, now the printer has another mDHCP address, but I can reach the server, also upload is working., And existing files on the RepetierServer I can print!

Also the filesystem is not full.
RepSrv 0.94.3 is running on a Raspberry.

Whats wrong ?

You can not print stl files! stl is the 3d description. You need to convert it to gcode first using a slicer of your choice like you did for the cube. Then upload the gcode and you will see it renders and prints.
