Sorry for the double post, but I might have a better chance to get some help by creating a brand new topic. My issue was initially posted here: > [@BTCPay cannot access internet. Traffic blocked by container?](http://community.umbrel.com/t/btcpay-cannot-access-internet-traffic-blocked-by-container/6451/8): > > I’m having a similar issue. Running BTCPaySever on Umbrel. Installed nginx to access it through reverse proxy in order to expose the API for my app server. No matter what price source I select, I get the following error ERR\_RATE\_UNAVAILABLE. I honestly have no idea as to how I would troubleshoot this. I DID have pi-hole installes, but I never configured it. I have since removed it. Any ideas to share? Edit: Interesting to notice that when I go into the “Plugin” section, I also get the Rem… **TL;DR** - I’m running BTCPaySever on Umbrel. - I’ve installed nginx to access it through reverse proxy in order to expose the API for my app server. It works like a charm. ([btcpay.latranchee.com](http://btcpay.latranchee.com)) - BTC Pay Server can’t communicate with the outside world. I honestly have no idea as to how I would troubleshoot this. I DID have pi-hole installes, but I never configured it. I have since removed it. I’m familiar with how to configure a linux server, but I’m no expert. I assume it has something to do with the networking settings on my node. But I have NO idea where to start. Any help would be greatly appreciated! 🙌 ---

If you eliminate all possible causes, like Pi-hole and you are sure that you have a clear traffic to outside. then you should try to discuss this aspect with the guys from BTCPay server on [https://chat.btcpayserver.org/](https://chat.btcpayserver.org/) I don’t see how Umbrel guys can help you with a specific issue on BTCPay. ---

> [@DarthCoin](#): > > You are sure that you have a clear traffic to outside That’s the issue, I’m not sure that’s the case. I don’t know the stack used to route the traffic to the docker images and I don’t know how to troubleshoot that part. Is there a command I can run from inside the docker container to check that? * * * **EDIT** In fact, I’m pretty sure that’s the problem. Here’s what happens when I ping from inside the Pi: ![image](https://canada1.discourse-cdn.com/flex030/uploads/getumbrel/original/2X/6/6c1dbf8e05a8864054f4ead8631f7206be04ccaf.png) Everything’s good. Now here’s what happens when I try to install net-tools inside my docker container: ![](https://canada1.discourse-cdn.com/flex030/uploads/getumbrel/original/2X/a/a8cbab8e0237d8d71d38a664bf003773bce4da39.png) It can’t reach the Debian servers. If that helps, here’s a list of my docker containers: ![](https://canada1.discourse-cdn.com/flex030/uploads/getumbrel/original/2X/3/3d28dc40fb2fa300436f6aeff3b387a9aea2d803.png) So I’m pretty sure it’s safe to assume the problem is with the Pi configuration and not the BTCPayServer instance. Is there some sort of internal firewall that I need to configure? ---

FYI, problem was solved after the latest Umbrel update. Either that did it or the reboot! 🙌
