Looking at the change logs from the other firmwares I think d230 has not been updated with these changes:
patch OBiapp to bypass GVSIP provisioning lock
patch OBiapp to fix the bug where OBi forgot to set the TLS SNI hostname resulting in “No Response From Server” when attempting to connect to GV
NEW: add GV config instructions to webgui
NEW: make full root Certificate Authority list user-editable at /scratch/rootca.pem (by default symlinked to 2024-11-26 mozilla/curl root CA list from curl.se/ca/cacert-2024-11-26.pem)
I tried copying the ITSP Profile A settings as best I could from a working OBI300 but I was unable to get it to work with a status of: ‘Register Failed: 400 Bad Request’.
