最近我配置了 Site-2-Site VPN 隧道，但收到以下錯誤：
3 Feb 27 2018 09:21:57 Tunnel Manager has failed to establish an L2L SA. All configured IKE versions failed to establish the tunnel. Map Tag= TTL_map. Map Sequence Number = 1.
3 Feb 27 2018 09:21:57 Group = 10.249.7.13, IP = 10.249.7.13, Removing peer from correlator table failed, no match!
3 Feb 27 2018 09:21:57 Group = 10.249.7.13, IP = 10.249.7.13, QM FSM error (P2 struct &0x00007fff383352e0, mess id 0xb3f7fd67)!
我研究並應用了他們推薦的許多解決方案，但沒有結果。
我要怎麼解決這個問題？多謝！
