A customer using the previous Wowza server engine version 3.1 purchased a new license and installed version 4.8.5.
A program operated by the customer was operated in a format that accesses a specific time information file using a single vod file, but if it is operated with version 4.8.5, the file accesses the wrong location and there is a problem that the file cannot be accessed. . Please let me know what needs to be fixed.
