What you expected to happen:
Load VPN configuration either manually by browsing and selecting each cert and key file, or importing a .ovpn file. TA key name is "my_ta.key". Turn on VPN and it connects.

What happened instead:
Load VPN configuration either manually by browsing and selecting each cert and key file, or importing a .ovpn file. TA key name is "my_ta.key". In the GUI, key is renamed to "myta.key". Turn on VPN and connection is immediately rejected with authentication error.

Workaround:
The GUI will always remove the underscores from the filename once loaded, so the only way to get it to read correctly is to remove the underscores from the file itself (e.g. "myta.key"). Once this is done, the VPN connects without issue.

Thank you for bug report. Could you do
$ journalctl -f
then trigger the issue and copy the log to the bug report?

Testing locally the '_' is removed from the name in the UI but doing

$ nmcli connection edit 'Connection_name'
p vpn.data

displays the correct filename with an '_'
