Agent not sending data to the server

[lnicola]

Hi, everyone! I'm just giving parca a try on my computer, using the binary releases on GitHub. The server runs fine (including scraping if I enable it), but the agent doesn't seem to send it any data. I'm running it with:

$ sudo ./parca-agent --remote-store-address=localhost:7070 --remote-store-insecure --analytics-opt-out --python-unwinding-disable --ruby-unwinding-disable --log-level=debug

parca itself is listening on 7070, but the agent doesn't show up under Targets. I also tried --remote-store-address=localhost:7073, but there was no error.
