host not found in upstream "mempool.space

With updated nginx (based on bullseye repo) the nginx conf of mempool is throwing an error:

Dec 19 21:35:19 raspberrypi nginx[703]: nginx: [emerg] host not found in upstream "mempool.space" in /etc/nginx/snippets/mempool.conf:38
Dec 19 21:35:19 raspberrypi nginx[703]: nginx: configuration file /etc/nginx/nginx.conf test failed
Dec 19 21:35:19 raspberrypi systemd[1]: nginx.service: Control process exited, code=exited, status=1/FAILURE
Dec 19 21:35:19 raspberrypi systemd[1]: nginx.service: Failed with result 'exit-code'.
Dec 19 21:35:19 raspberrypi systemd[1]: Failed to start A high performance web server and a reverse proxy server.
--> CHECK CONFIG: sudo nginx -t

Trying to remove this lines for now …

	location /api/v1/donations {
		proxy_pass https://mempool.space;
	}
	location /api/v1/donations/images {
		proxy_pass https://mempool.space;
	}

people will wonder why we are pinging mempool.space on clearnet.

To be clear, this is not a “phone home” or anything like that, it’s an nginx.conf proxy so if you hit the donations/contributors API via the About page it will connect to us, but you made a good point that this should be done over Tor - we can improve that

OK final testing looks good. Closing this issue for v1.7.2 release.
