I’m running into an issue performing a firmware upgrade on the MAX BR1 Mini, both LTE and LTEA versions. I am attempting to go to 8.1.1, however in testing I’ve only been able to do it successfully today from 8.1.0. The upgrade is being performed via the automatic upgrade function inside the Web UI. Check for Firmware succeeds and finds 8.1.1, and Download and Upgrade starts the process successfully.
I did packet capture and see that the Mini reaches out to download.peplink.com and a TLS 1.2 session is initiated. It appears that the TLS session is established and then the remote side sends a FIN, ACK. The upgrade does not proceed and just sits there.
I am seeing this behavior on multiple carriers and modems, ruling out a device issue. I have not yet tried 8.0.1 or 8.0.2 to see if they upgrade.I did try 8.0.0 and saw the same failure.
Is there a KB I missed in my search or does anyone have any insight into what’s going on? This used to work on 7.1.0 as I used it to skip having to install 7.1.2, then up to 8.x previously.
