I’m getting and error when trying to flash AGX board to latest 5.2.6 version. On Monday I updated a different board successfully, but today I’m getting some kind of server error

11:16:21 ERROR: Flash Xavier A - flash: Head request failed. Server error: 403 - Forbidden. Url:

Here is exported debug logs. Also, I’m tried upgrading to latest SDKmanager ver but got the same error. (875.7 KB)

Dear @gordon1zrra,
Are you using the same host to flash new board? If not, could you check flashing with
the same host?

Yes, I’m using same host computer. Initially I tested with older version of SDKManager that worked earlier this week (1.7.1 something), but then updated to latest when I got this error. Is it possible there is some permission problem on my nvidia account?


I just retried flashing today and it’s working now. I didn’t change anything on my side, not sure what helped.

Issue can be closed, thanks.
