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 Remote plugins lookup failed. Try again later. error. So outbound connection from the btcpay container is clearly not working.
