Create API not working

I am not able to generate Merchant Key due to SSL expire on lighting.filipmartinson.com.

I am using below command

In Windows Powershell, execute these commands one by one:

$env:BTCPAY_URL=‘https://mydomain.com/
$env:BTCPAY_KEY=‘KEY’
$env:BTCPAY_PAIRCODE=‘PAIRCODE’
node -e “const btcpay=require(‘btcpay’); new btcpay.BTCPayClient(process.env.BTCPAY_URL, btcpay.crypto.load_keypair(Buffer.from(process.env.BTCPAY_KEY, ‘hex’))).pair_client(process.env.BTCPAY_PAIRCODE).then(console.log).catch(console.error)”

After running this, I am getting SSL error.
