When connecting to my server through my domain, I get connection error. however, on a VPN it connects just fine

tk flag

New poster here so unsure if this is the correct stack exchange.

But basically, I use NPM (Nginx Proxy Manager) to direct internet traffic to various VMs running on my hub server running proxmox.

Whenever I try to connect to an internet SSL-based web application such as the web UI for NPM or Nextcloud, my web browser gives me a connection error. However, when I try to connect to the same domain that gave me a connection error through a VPN connection, the connection works just fine.

Why can't I connect to my own domains while being just on my normal connection no VPN?

Just a few things: Everything is hosted on 1 single public IP.

Every web app has its own VM on an unfirewalled proxmox server (Every vm has its own built-in firewall, with relevant ports forwarded)

My domain name is: ambient-sky.co.uk

The VPN I use is just opera GXs proxy server.

Any ideas/tips would be helpful as I've never experienced this before.

If any logs or configurations are needed then I'd be happy to oblige.

No VPN

VPN enabled

Does this answer your question? [Loopback to forwarded Public IP address from local network - Hairpin NAT](https://serverfault.com/questions/55611/loopback-to-forwarded-public-ip-address-from-local-network-hairpin-nat)

No. Since I'm not using Hairpin NAT. Nor do I even know what that is :)

Do you use NAT? You include no information on your topology. My suspicion is that your problem is that you *don't* use hairpin NAT - hence the duplicate. Please read it.

to solve the problem, we need: /etc/network/interfaces, /etc/nginx/ where we see how you proxy it, the rest we can figure out later but using admin panel will not make it easier

@vidarlo Probably gonna need an explanation on NAT. I also have no idea what topology means. Do you mean my setup? I thought I explained that.. I did read it, and understood none of it. Please reclarify

@djdomi No such file or directory for /etc/network/interfaces. No such file or directory for /etc/nginx. NPM is running in a docker container.

@AmbientSkai That's a good hint that this question belongs at [superuser.com](https://superuser.com). This site is for business IT problems, and we generally expect some level of knowledge. Posting home user questions on here tends to be unpleasant.

Okay, I'm not 100% sure if it was something I did or if my ISP forked up somewhere along the line. But now its working just fine

I sent an email to them asking if it was something on their end on why I couldn't locally resolve my own public IP. Woke up today, and now I can for some reason and my Domains are working locally again.. I never had a response from them on my email.

Sorry if I wasted anyone's time.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
