Hi,
I'm facing the same issue : KeepassXC-Browser is not able to connect to Database.

I'm under Windows 10 Familly with the brower Firefox Quantum 59.0.1 (64 bits) and my KeePassXC is 2.3.1. The plugin is 1.0.1

and then, no way to connect here

And the last thing is : the plugin KeePassHttp-Connector works fine.

So, without answer I had to manage by myself and I finally found a solution. Thanks to varjolintu ;-)
So the solution is there #1559

Not exactly the same issue : in my situation the connected database was shown.

@Larry3460 : did you follow the migration process ?
https://keepassxc.org/docs/keepassxc-browser-migration/

In my situation it seems working without bug today ...
I Will comme back if it goes wrong again

[Larry3460]

Yes, I did.

For me, this error was occurring in ubuntu 16.04 because apparmor blocks access to /usr/bin/keepassxc-proxy. (edit: for firefox)

I installed keepassxc using the ubuntu ppa.
