BTCPAY_ADDITIONAL_HOSTS redirects to main host

Hi,

I've been using BTCPay for several months with a single domain. However, now i need to add a second domain, and i've encountered some issues.

My current BTCPay configuration: #!/bin/bash export COMPOSE_HTTP_TIMEOUT="180" export BTCPAYGEN_OLD_PREGEN="false" export BTCPAYGEN_CRYPTO1="btc" export BTCPAYGEN_CRYPTO2="xmr" export BTCPAYGEN_CRYPTO3="ltc" export BTCPAYGEN_LIGHTNING="none" export BTCPAYGEN_REVERSEPROXY="nginx" export BTCPAYGEN_ADDITIONAL_FRAGMENTS="opt-save-storage-xs;opt-add-cloudflared" export BTCPAYGEN_EXCLUDE_FRAGMENTS="" export BTCPAY_DOCKER_COMPOSE="/root/BTCPayServer/btcpayserver-docker/Generated/docker-compose.generated.yml" export BTCPAY_BASE_DIRECTORY="/root/BTCPayServer" export BTCPAY_ENV_FILE="/root/BTCPayServer/.env" export BTCPAY_HOST_SSHKEYFILE="" export BTCPAY_ENABLE_SSH=true export PIHOLE_SERVERIP="" export BTCPAY_ADDITIONAL_HOSTS="subdomain.newdomain.com" if cat "$BTCPAY_ENV_FILE" &> /dev/null; then while IFS= read -r line; do ! [[ "$line" == "#"* ]] && [[ "$line" == *"="* ]] && export "$line" done < "$BTCPAY_ENV_FILE" fi

As you can see, i'm using Cloudflare tunnels. However, i don't think the issue is related to that. I've correctly set the host header on the tunnel configuration.

When using the subdomain.newdomain.com to connect, i get a 503 error. Looking at the Nginx configuration on the container, i can see the subdomain is missing. I've tried deleting the Nginx container and running btcpay-update, but it didn't fix the issue.

Below is the Nginx config (removed the irrelevant part): `# Mitigate httpoxy attack (see README for details) proxy_set_header Proxy ""; server { servername ; # This is just an invalid value which will never trigger on a real hostname. listen 80; access_log /var/log/nginx/access.log vhost; return 503; } server { servername ; # This is just an invalid value which will never trigger on a real hostname. listen 443 ssl; http2 on; access_log /var/log/nginx/access.log vhost; return 503; ssl_session_tickets off; ssl_certificate /etc/nginx/certs/default.crt; ssl_certificate_key /etc/nginx/certs/default.key; } upstream btcpay {

Can be connected with "generated_default" network

I just noticed github didn't properly format the configs :( Sorry about that

Problem solved! I had to run btcpay-setup, not btcpay-update export BTCPAY_HOST="domain.com" export BTCPAY_ADDITIONAL_HOSTS="new.domain.com" . ./btcpay-setup.sh -i
