Zero download speed at times

[Terrance]

On several occassions I've found the download speed to be reported as zero:

$ speedtest-go

    speedtest-go v1.6.10 @showwin

✓ ISP: ...
✓ Found 20 Public Servers

✓ Test Server: ...
✓ Latency: 8.735036ms Jitter: 851.809µs Min: 7.714099ms Max: 10.439103ms
✓ Download: 0.00Mbps (used: 0.00MB) (latency: 8ms jitter: 0ms min: 6ms max: 9ms)
✓ Upload: 95.58Mbps (used: 113.94MB) (latency: 8ms jitter: 0ms min: 7ms max: 11ms)

This happens both on Arch Linux (using the speedtest-go AUR package) and on Android in Termux (also 1.6.10), though it seems to be a temporary issue that comes and goes -- download speed is currently reported correctly (~450Mbps) on both devices.

Running with -d I can see the download URL being repeatedly logged, whether the speed is being reported correctly or not:

I think this is caused by the third-party server being temporarily unreachable. Does this always happen on a certain server?

[Terrance]

It's possible, will keep an eye on it and make a note of the host next time it happens (tried a few times today but yet to repro).

✓ Test Server: [9060] ... Norwich (United Kingdom) by Voicehost Ltd
✓ Latency: 8.713507ms Jitter: 535.181µs Min: 7.695769ms Max: 9.533825ms
✓ Download: 0.00Mbps (used: 0.00MB) (latency: 8ms jitter: 0ms min: 6ms max: 9ms)
✓ Upload: 96.34Mbps (used: 114.84MB) (latency: 9ms jitter: 0ms min: 6ms max: 10ms)

Yes, looks like it's specific to this server -- repro'd on two devices hitting the same server, but both are happy when they choose other hosts.

.\speedtest-go.exe -s 9060

    speedtest-go v2.0.0-beta1 @showwin

✓ ISP: *.*.*.* (x x) [*, *]

Yes, I can reproduce this on this server.

What is certain is that the server 9060 is actively rejecting download requests from user-agent showwin/speedtest-go x.y.z

Related #159

All download requests containing the speedtest-go field in the first position in the user-agent are rejected.
I think this is a deliberate setting by the third-party server. Maybe it touches their interests.
This is a bad start and indicates someone is abusing this repo.

I can reproduce this issue with 53972 (Dish Wireless).

I can reproduce this issue with 53972 (Dish Wireless).

I think we can add a flag --user-agent to the cli, so that users can modify the default user-agent to avoid being banned by the server.

@r3inbowari thanks! Would it make sense to display N/A or some kind of error string instead of a confusing zero speed number in cases like this?

[r3inbowari]

⠦ Download: N/A Mbps (latency: 374ms)

⠦ Download: N/A (latency: 374ms)

or?

[vaygr]

The second one looks great to me.
