The digital ocean agent has been working correctly for sometime but recently I have veen receiving the the message "Not receiving metric data" when I look at the Graph section of my droplet.

My droplet has only a simple NodeJS site with an Nginx proxy and a single static site.

UFW is enabled with all outgoing allowed and 80, 443 and SSH incoming allowed.

• Could the firewall be blocking the do-agent from reporting metrics?
• Could the Nginx usage of 80 and 443 be interfering with the do-agent?

Any suggestions would be welcomed.

Thanks.
