Is your domain also going through Cloudflare? Cloudflare's Rocket Loader feature causes this specific behaviour you just described. It's recommended to turn it off when using Coolify: https://coolify.io/docs/troubleshoot/dashboard/dashboard-slow-performance#_3-addressing-cloudflare-rocket-loader

Thank you for your response. I had already reviewed that page before posting my issue. However, my domain is not routing through Cloudflare. For context, the domain was purchased from Namecheap.

Would you like to include any specific error or behavior you’re encountering to help them troubleshoot further?

Do you see any errors in browsers console or network tab? Do you have that behaviour on both, when you access coolify via th Instance Domain and through your server ip and port 8000?

Q: Do you see any errors in browser's console or network tab?
A: There are no errors in the console, but in the network tab, I noticed a (failed) net::ERR_QUIC_PROTOCOL_ERROR.QUIC_TOO_MANY_RTOS message.

Q: Do you have that behaviour on both, when you access Coolify via the Instance Domain and through your server IP and port 8000?
A: The issue only occurs when accessing via the domain. It doesn't happen when using the server IP and port 8000. (Note: I'm using Caddy server as a reverse proxy.)
