Provisioning only works on startup

Thanks for reaching out and letting us know your question.

Base on your info, "tftp to file failed, code = -168, msg = , retry = 1", it means that the file doesn't exist or is forbidden to visit. So please kindly check your TFTP server first.

Thank you in advance.

Regards,
Jay

Hi Jay, thanks for your reply. So the TFTP server is all functioning as it should - in fact, I have two phones side by side, one still running 52.84.0.15 and the other I upgraded to 52.84.0.125. Both have identical provisioning settings.

The 0.15 one works fine, both on power up and manual provisioning. The 0.125 one provisions on power up, but when I manually provision, it immediately says ‘failed’.

The fact that it provisions successfully on power up suggests that the provisioning settings are all correct though.

I just tried downgrading to 84.0.90 and auto provisioning manually works as expected. Upgrading back to 0.125 gives me the ‘configuration update failed’ message every time when provisioning manually.
