Cannot read from socket

I'm trying deploy the exporter via Docker but I have the following error:

This is my docker-compose with differents exporters with prometheus and grafana and the other ones are working fine except speedtest:

I had a similar issue when using billimek/prometheus-speedtest-exporter the other day, I've opened an issue there.:

[2024-04-03 12:06:27.335] [error] Test failed to complete: Cannot read from socket:

I've tested with network_mode: host and this seems to solve the issue, although some non-fatal warnings about Cannot read from uninitialized socket can still be seen in the runs.

It seems like an issue with ookla-speedtest being run inside a docker container with bridge networking, but I am still failing to understand why this might be.
