Public bug reported:

On Ubuntu 22.04.5 with network-manager-openconnect, we got failed to
connect SSL VPN (Palo Alto Global Protect VPN), and we can connect to
the same server if we use Ubuntu 20.04.6

On Ubuntu 22.04:
> libopenconnect5/jammy,now 8.20-1 amd64 [インストール済み、自動]
> network-manager-openconnect-gnome/jammy,now 1.2.6-4 amd64 [インストール済み]
> network-manager-openconnect/jammy,now 1.2.6-4 amd64 [インストール済み、自動]
> openconnect/jammy,now 8.20-1 amd64 [インストール済み、自動]

On Ubuntu 20.04:
> libopenconnect5/focal,now 8.05-1 amd64 [インストール済み、自動]
> network-manager-openconnect-gnome/focal,now 1.2.6-1 amd64 [インストール済み]
> network-manager-openconnect/focal,now 1.2.6-1 amd64 [インストール済み、自動]
> openconnect/focal,now 8.05-1 amd64 [インストール済み、自動]

We expect that the network-manager-openconnect successfully connects to our VPN 
server on Ubuntu 22.04, as same as Ubuntu 20.04.
However, we got failed to connect to VPN server on Ubuntu 22.04, even 
successfully on Ubuntu 20.04.

We attach the syslog output on VPN connection with replaced our domain
names and IP addresses both on 20.04 and 22.04.

FYI: 
I found that the issue is fixed by using v1.2.10 source of 
network-manager-openconnect.
I have tried as follows:
1. download source packages from 
https://packages.ubuntu.com/focal/network-manager-openconnect (yes we use focal 
source, not tried jammy source),
2. extract and overwrite them by using v1.2.10 source of 
https://gitlab.gnome.org/GNOME/NetworkManager-openconnect/-/tags/1.2.10,
3. apply small patches to fix build error on this version,
4. build the package by `dpkg-buildpackage -us -uc -b`,
5. remove network-manager-openconnect and network-manager-openconnect-gnome and 
install packages built above,
6. connect to VPN, then successfully connected.
