Thank you for your question,
FM6300 devices do not support "FotaWeb" feature,
Please follow the link for device requirements to use the "FotaWeb" platform:
||1. All FMBXXX devices except for FMB64X should have at least 01.03.03.Rev.00 firmware version installed.
2. FMB64X should have at least 00.02.05 version installed.
FM6300 can be updated and configured over the air using "FOTA" application
Application requires license key, this should be requested from your sales mananger.
Hope this helps,
