Subject: [strongSwan] Getting "IDr payload missing" error in strongswan version 5.2.0

Hi All

I am facing an issue where I am getting an error message "IDr payload missing" though we have configured the rightId properly.
"rightid=@iprc.nlt.in<mailto:rightid=@iprc.nlt.in>" in conn default section.

Scenario:
1>Three tunnels are up between host and Gateway
2>unplug the backhaul (eth cable) and plug it back
3> Two tunnel comes up correctly, but one is failing IKE_AUTH failed for reason "IDr payload missing"
And in wireshark it show IKE_AUTH message is malformed packet.

But same configuration is working fine, if we reboot our host once the problem occurred.

Please let me know what could be wrong. OR is there any issue in building IKE_AUTH request1 message.

Thanks in Advance,
Sachin
