Cannot connect to KeePassXC on Windows10/Vivaldi about keepassxc-browser HOT 7 CLOSED

You need to enable Vivaldi browser within the keepassxc browser settings.

Vivaldi registry configuration is located here: HKEY_CURRENT_USER\\Software\\Vivaldi\\NativeMessagingHosts\\

https://github.com/keepassxreboot/keepassxc-browser/wiki/Troubleshooting-guide#windows

from keepassxc-browser.

I did enable it. There is one button for all Chrome, Vivaldi, and Brave which is checked.

from keepassxc-browser.

Registry was edited like this:

from keepassxc-browser.

I also restarted my PC

from keepassxc-browser.

Check:

• The executable path in that JSON file is correct
• You can start keepassxc-proxy.exe manually

from keepassxc-browser.

I copy pasted the path of the JSON file in the file explorer and it directly opened in Notepad:

{
    "allowed_origins": [
        "chrome-extension://pdffhmdngciaglkoonimfcmckehcpafo/",
        "chrome-extension://oboonakemofpalcgghocfoadofidjkkk/"
    ],
    "description": "KeePassXC integration with native messaging support",
    "name": "org.keepassxc.keepassxc_browser",
    "path": "C:\\Program Files\\KeePassXC\\keepassxc-proxy.exe",
    "type": "stdio"
}

I also started the keepassxc-proxy.exe manually but still receive the same error message in the Extension:

from keepassxc-browser.

I also sometimes get the following errormessage:
[Error keepass.js:418] KeePassXC-Browser - 9: Key exchange was not successful.
