Reported using DrKonqi

Comment 1 Thomas Rother 2024-10-07 09:37:01 UTC

This bug is still reproducible after the last Tumbleweed update. Therefore I can not open my business VPN which I need every day. Any ideas? Can I help debugging somehow?

Comment 2 Thomas Rother 2024-10-14 06:12:41 UTC

Distro: openSUSE Tumbleweed

Initial selection of the openconnect connection group is possible. The crash appears when entering username and password. Sometimes its crashing directly (see drkonqui data). In most cases the UI is just unusable, the "login" button for username/password disappears/flickers. This looks like a functional regression from 6.1.x. Nmcli must be used as fallback.
