I am working in a lab with VMware virtual machine and when I do VPN it throws the following error: ike phase 1 negotiation fails as initiator, main mode failed SA: 192.168.1.1[500]-203.0.113.40[500]Due to time.
My firewall B is on another machine with another VM. Can you help me please?

You need to start troubleshooting from firewall B.
If there is any mismatch then B will sit silent and will not tell "attacker" what config it should change to get successful VPN connection.
As you see initiator only sees "timeout".
Firewall B logs on the other hand will tell you why VPN failed.

Hello,
To add to this, I would check the ikev1 configuration on both sides to verify they are identical.

Make sure the reachability is good between both nodes.
If there is NAT involved then enable NAT-T.
