File *.htm with NUL content

Player Version

3 R301.1-301

Issue

We have a series of players that reproduce a layout containing some embedded web pages with url on the local network.
All this works regularly except on some specific players where on a regular basis (every two to three days) the pages within the layout are no longer displayed. After some tests we realized that the “solution” is to:

  • Close the player
  • Delete the * .htm files from the Xibo Library folder
  • Restart the player
    Comparing the htm files before and after we saw that all the parts of the layout that were not reproduced had an htm with all [nul] inside and after having downloaded them a standard html appeared.

File HTM before delete


Code in red square are two html comment: VIEWPORT=140x140 and CACHEDATE=10/05/2022 05:03:03

File HTM after player download


Code in red square are two html comment: VIEWPORT=140x140 and CACHEDATE=10/05/2022 09:48:32

How we can solve this issue? We have no idea what the source of the error might be, especially since it only happens on some players and always on the same ones (one in particular where we also tried to reinstall the software from scratch without success).

Thanks in advance.

Has anyone had a similar problem or have any ideas on a possible solution?
