The password is pre-filled and you can click + the ok button to reconnect. The error occurs sometimes very often (e.g. 10 times/minute) or seldom (only one per day). The problem occurs in Xubuntu 20.04.1 LTS since update to kernel 5.4.0-56 (5.4.0-58 too). With other Xubuntu versions (e.g. 18.04 LTS) or kernel 5.4.0-54 or earlier the problem did not appear. Other OS (eg W10 or div Android) do not see this problem too.
