And so on. In the nginx log there's the following:

2020/06/21 15:11:44 [emerg] 15#15: host not found in upstream "www.percona.com" in /etc/nginx/conf.d/pmm.conf:179
2020/06/21 15:11:49 [emerg] 154#154: host not found in upstream "www.percona.com" in /etc/nginx/conf.d/pmm.conf:179
2020/06/21 15:11:59 [emerg] 180#180: host not found in upstream "www.percona.com" in /etc/nginx/conf.d/pmm.conf:179

Anyone else having this problem?
