If the Agent is not connecting to Probely, please ensure that your [firewall](#network-requirements) is properly configured.

Alternatively, the agent can use an HTTP proxy to connect to Probely if the `HTTP_PROXY` environment variable is set on the `docker-compose.yml` file.
While the agent can use an HTTP proxy or a direct TCP connection to Probely, this can cause poor network performance. For more information, see this article about the [TCP Meltdown](https://web.archive.org/web/20220103191127/http://sites.inka.de/bigred/devel/tcp-tcp.html) problem. We **strongly recommend** that you allow the agent to connect to `54.247.135.113` and `44.212.186.140` on `UDP` port `443`.
