Can't believe I missed that.
But yes that was the error:

Fixed: Accepted Methods are stored as follows in DBI::ProxyServer:

$o->{'XXX_methods'}    = {
    'DBI::ProxyServer' => {
        'Version' => 1,
        'NewHandle' => 1,
        'CallMethod' => 1,
        'DestroyHandle' => 1
        },
    'DBI::ProxyServer::db' => {
        'prepare' => 1,
        'commit' => 1,
        'rollback' => 1,
        'STORE' => 1,
        'FETCH' => 1,
        'func' => 1,
        'quote' => 1,
        'type_info_all' => 1,
        'table_info' => 1,
        'disconnect' => 1,
        },
    'DBI::ProxyServer::st' => {
        'execute' => 1,
        'STORE' => 1,
        'FETCH' => 1,
        'func' => 1,
        'fetch' => 1,
        'finish' => 1
        }
    };

Add
'connected' => 1,
To the hash_ref:

'DBI::ProxyServer::db' => {
            'connected' => 1,
        'prepare' => 1,
        'commit' => 1,
        'rollback' => 1,
        'STORE' => 1,
        'FETCH' => 1,
        'func' => 1,
        'quote' => 1,
        'type_info_all' => 1,
        'table_info' => 1,
        'disconnect' => 1,
        },

Just restart the proxy and that's it!
