My device is usg20-vpn
The original version was 4.16. To update to the latest version 5.36.
I directly download the bin file of 536ABAQ1C0 from the official website
Upload to the device
But after the update, I can't log in with my account password.
I can't get in even if I use the default account admin password 1234
I wonder if any of you have encountered the same problem?
Can you give me some answers or suggestions, thanks

    1: try to flush the cache of your browser
    2: try to login using the "incognito" mode of your favourite browser
    3: try to login using another browser
    4: try to write down your password on notepad/something similar before inputting that on the password field of your device

    Question: does your password have any special character(s)? Would you please share which eventually is?

    My password is 1234 so no special characters

    In the end, I restored the version back to the original version, and then threw back the backup config, so it was restored to the original state

    The main reason is that I don’t know if I can upgrade the version directly, or there must be an upgrade path
