No Webinterface if startup fails to contact coingecko (internet connection down) AND no auto resume of operation thereafter

Describe the bug I noticed that during a power outage where my solar battery powers the house (with a small interruption, hence the reboot) and the DSL connection is still down, the btcpayserver does not resume normal operation even after the dsl comes back on.

Looking at the logs I noticed, that btcpay is not listening on it’s service port, the logs show this:

warn: PayServer:      Error while contacting exchange coingecko: Resource temporarily unavailable (api.coingecko.com:443)
warn: PayServer:      Error while contacting exchange coingecko: Resource temporarily unavailable (api.coingecko.com:443)

To Reproduce the bug Steps to reproduce the reported bug:

1. on a locally running btcpay setup, disconnect DSL and power from your Pi
2. reconnect power and wait for it to boot
3. When trying to connect to it through the home network, you’ll notice a 503 error
4. to resume normal operation when the DSL is back on you need to run btcpay-restart.sh

Expected behavior

I would have expected btcpayserver to bind to it’s port even if coingecko is unavailable or at least continue trying to reach coingecko and automatically restore normal operation upon resuming of the internet connection.

Your BTCPay Environment (please complete the following information):

• BTCPay Server Version: v1.5.2.0
• Deployment Method: Docker
• Browser: Chrome

no power outages as of recently. So the issue didn’t show up again. I would close it now and reopen if it happens again.

@petzsch Is this still an issue for you?
