EOF on Speedtest when starting node
Describe the bug A few users are experiencing issues with exactly one of their nodes after stopping it and restarting it. The error is an EOF immediately after beginning the Speedtest with speedtest.net
To Reproduce Run the node
$ docker run --rm --interactive --tty --volume ${HOME}/.sentinelnode:/root/.sentinelnode --volume /lib/modules:/lib/modules --cap-drop ALL --cap-add NET_ADMIN --cap-add NET_BIND_SERVICE --cap-add NET_RAW --cap-add SYS_MODULE --sysctl net.ipv4.ip_forward=1 --sysctl net.ipv6.conf.all.disable_ipv6=0 --sysctl net.ipv6.conf.all.forwarding=1 --sysctl net.ipv6.conf.default.forwarding=1 --publish 52618:52618/tcp --publish 20640:20640/udp sentinel-dvpn-node process start

Expected behavior
For the Node to run as prior to restarting it. It seems there is a problem Fetching the servers in utils/speedtest.go This might be a speedtest thing, but I dunno, since it works on all other nodes. It could be a host problem on our end.
Desktop (please complete the following information):
- OS: Ubuntu 20.04
- Version: v0.3.2
Additional context I successfully spun up a new node and everything worked. It is just on exactly one node for many users. I downloaded the speedtest CLI by Okala and that did work.
Same for me since a few months. Config: Debian 11 My only node get stuck. I tried to reinstall it from scratch and it does not improve. It seems it is only for French nodes.
I think this is an issue with speedtest-cli software since the dVPN node software uses it.
I tried to use the speedtest-cli (pip install speedtest-cli or sudo apt install speedtest-cli) on a server that is located in France and it didn't work. Said it couldn't connect to speedtest.net server. I think this issue is directly isolated to nodes in France.
The github https://github.com/sivel/speedtest-cli says that they will not fix any issues any more. Maybe adopt the speedtest.net CLI in future dVPN node releases??
The CLI works for me. I installed it using
sudo apt-get install curl
curl -s https://packagecloud.io/install/repositories/ookla/speedtest-cli/script.deb.sh | sudo bash
sudo apt-get install speedtest
Yeah Sentinel should use this one going forward. I think (not sure though), they are are using that github speedtest-cli version
Figured it out. It's a IP ban from speedtest.net -
IN speedtest-cli at line 1447 it calls a routine to get the servers from speedtest.net which can be traced back to line 1261 where it requests the server information to preform a speedtest from the url http://c.speedtest.net/speedtest-servers-static.php
running curl http://c.speedtest.net/speedtest-servers-static.php from any of my three Paris, France servers gives the same response:
$ curl http://c.speedtest.net/speedtest-servers.php

I'm going to e-mail speedtest as they provided me their e-mail on twitter.
Same error from my node. I get a correct list from another country. So they blocked all French IPs it seems.
Sentinel uses https://github.com/showwin/speedtest-go/ And in https://github.com/showwin/speedtest-go/blob/e55185e1a09e7a176b9a545fcf619246c99f24fc/speedtest/server.go#L20 they use https://www.speedtest.net/speedtest-servers-static.php
Solved with last release!
