Connecting a Cisco switch to a HP Procurve

Network will be mostly HP Procurve with a few Cisco switches.
Network comprises 2 vlans.       Vlan 1 192.168.0.0/24     Vlan 2 192.168.1.0/24

With 3 switches as shown in drawing connected with just an ip address on the vlan1 interface, all switches can ping each other via telnet.
As soon as I configure the tagging/trunking, I lose connectivity to the cisco switch.
If I run “sh cdp nei” from the HP “Switch2”, it can see both the HP “Switch1” and the Cisco “Switch3”
If I run “sh cdp nei” from the Cisco “Switch3”, it doesn’t show anything.
Running a “Sh int trunk” from the cisco shows that its mode is on, its encapsulation is 802.1q and its status is trunking.
Once the vlan 1 is working, i'll add the second vlan
Switch 1
hostname "Switch1"
vlan 1
   name "DEFAULT_VLAN"
   untagged 2-24,A1-A2,B1-B2
   tagged 1
   ip address 192.168.0.10 255.255.255.0

Switch 2
hostname "Switch2"
vlan 1
   name "DEFAULT_VLAN"
   untagged 3-24,A1-A2,B1-B2
   tagged 1-2
   ip address 192.168.0.20 255.255.255.0

Switch 3
hostname "Switch3"
interface GigabitEthernet1/0/1
 switchport trunk allowed vlan 1
 switchport mode trunk

interface Vlan1
 ip address 192.168.0.30 255.255.255.0


kind regards
