ike2 ipsec stuck in phase1 same config to other vpn gateway is working no clue how to fix

Dear ALL,

I have some homeworker i tried to connect to one of our IPSEC router.

Homeworker is using a mikrotik behind a Hybrid modem (LTE+DSL) his router gets a NATED IP 10.0.0.0/24 GW is 10.0.0.138. User has dynamic public IPV4 IP.

194.XXX = public IP Homeworker 92.61.XXX VPN Server Static IP

I have one working tunnel from the homeworker to one of our offices. The other Office i cant successfully connect.
IPSEC Config is the same.

I made some wireshark captures:

From VPN Server to Homeworker (PCAP made on VPN Server)
from VPNSERVERtoHomeworker.PNG
Here from Homeworker to IPSECSERVER
homeworkertoipsecserver.PNG

what i can see ot homeworker mikrotik is that ipsec retransmit is comming several times till ipsec peer restarts. (exactly 30 seconds)


I guess it could be some NAT issue, but other VPN Connection is working so this is why i have no idea …


Please help me i have no idea how to solve it.

thank you

Mark
