@Radmin24 Hello! Recently there have been several users reporting similar issues. What is your Docker host's Linux version (e.g. Ubuntu 22.04), and what is your server's hosting provider? Please try the solution in this linked comment by building the August 2023 version of this Docker image. Let us know if that version resolves the issue for you.

Before the time, I began to rejoice. Still clients cannot connect.

Docker version 26.0.1, build d260a54 Ubuntu 22.04.4 LTS x86_64 hwdsl2/ipsec-vpn-server:debian git:(4c8bfa2)

It doesn’t work through mobile traffic, it takes a very long time to connect and there is no Internet at all.

@Radmin24 Thanks for the update. From the logs you provided, it looks like your mobile network provider may be blocking IPsec VPN traffic. This is indicated by the "retransmitting" and multiple "sent IKE_SA_INIT reply" related lines in your logs. Some countries use techniques (like the GFW in mainland China) to block VPN traffic. For these use cases, there isn't much you can do on the VPN server to make IPsec VPN work. However, you can instead try an alternative solution that is more resistant to blocking, such as Shadowsocks.
