unable to connect to the remote server via StrongSwan IPSec. Linux Debian 12

I have a problem connecting to a remote server via StrongSwan IPsec. I tried connecting using FortiClient IPsec on Windows, and everything worked fine. I was able to connect! However, when I tried to connect using StrongSwan, it didn’t work. I’d be very grateful for any support. This is my code in ipsec.conf config setup charondebug="ike 2, knl 2, net 2, dmn 2, mgr 2" nat_traversal=yes conn myvpn keyexchange=ikev2 authby=xauthpsk left=%defaultroute leftid= right= rightid=@ rightsubnet=0.0.0.0/0 ikelifetime=60m keylife=20m esp=aes256-sha2_256 dpdaction=clear dpddelay=30s dpdtimeout=120s auto=start This is my cod in ipsec.secrets @ : PSK "PSK_key" @ : XAuth "password"
