Problems with dedicates files to upload


I have problems to upload files to my RocketChat server. Some types are working fine, some get stuck at upload.

  • pptx and pnng are no problems,
  • pdf and HEIC are not working
    The upload always gets stuck at 0 or 7 % , no error occurs at the log.

I was looking for a solution online but all the solutions i found did not work.
The type restriction and allowed types are empty, upload size is for test purpose au -1.
