Update: I re-flashed the latest firmware , rebooted and was able to make a backup. However, after making some changes to the config and trying to make a backup the same 404 error appeared. Update 2: I have the same error now on one of the GS1900-24s (404 /tmp/running-config.cfg not found)
I have multiple Zyxel switches, mostly GS1900-24 running the same firmware version as the GS1900-48. From the same machine and browser I can make a backup on the GS1900-24s but not on the GS1900-48. I have tried on other browsers (IE6, IE10, Edge, Firefox, Safari, Chrome) and other platforms (Windows 10, Windows 7, XP,…
Thanks for the suggestion but it does not work as it is not a client side issue. The error is reported by the web server on the switch itself (lighthttpd?). The file path it refers to (/tmp/running-config) is not a windows path but a unix style path (I presume that the zyxel OS is some derivative of Linux).
