Yes I use my let's encrypt cert. Just import it using the server manager's gui into encryption and network

Thanks for the reply. I generated let's certificate using command: certbot certonly --standalone
I got four certificates from it which is
1. chain.pem
2. cert.pem
3. private.pem
4. fullchain.pem

I renamed chain.pem to chain.cer, then used chain.cer and cert.pem in Create New Certificate in vpn-server gui, But after that I was asked for a passphrase as shown in screenshot, But I didn't get or used any passphrase while creating these certs. I also tried using chain.cer and fullchain.pem but the result was same. Is there any mistake I am doing.

I beleive I have a .crt and a .key. I generate mine with pfsense acme plugin but just find the command that will give you theses files and you'll be ready to go

Yes I found the issue. I was using wrong files. This time I tried using first fullchain.pem and second private.pem And this time it didn't ask passphrase.
Thanks dear.
