Comment 20 for bug 1772705

I have the server side configured with ipsec.conf:

config setup
  charondebug="ike 0, enc 0, net 0"

conn %default
  keyexchange=ikev2
  mobike=no
  dpddelay=60
  dpdtimeout=180

conn lp1772705
  left=172.24.26.187
  leftcert=peerCert.der
  leftauth=pubkey
  leftsubnet=8.8.8.8/32
  right=%any
  rightsourceip=172.21.10.0/24
  rightauth=eap-mschapv2
  rightdns=1.1.1.1,1.0.0.1
  eap_identity=%any
  auto=add

With 5.6.2-1ubuntu2.4, I get random garbage as resolvers instead of 1.1.1.1 and 1.0.0.1:

I did multiple attempts varying rightdns= to push 1.1.1.1 and/or 1.0.0.1 but they all failed:
