Timeouts do not seem to be handled

[debuglevel]

Describe the bug
One of my BBB servers does not respond due to some reason.

# time curl https://bbb1.xyz.xyz/bigbluebutton/api/
curl: (52) Empty reply from server

real    0m50,020s
user    0m0,012s
sys     0m0,003s

Scalelite still thinks it's there:

# ./scalelite.sh servers
id: bbb1.xyz.xyz
        url: https://bbb1.xyz.xyz/bigbluebutton/api/
        secret: REDACTED
        enabled
        load: 5.0
        load multiplier: 1.0
        online
id: bbb2.xyz.xyz
        url: https://bbb2.xyz.xyz/bigbluebutton/api/
        secret: REDACTED
        enabled
        load: 0.0
        load multiplier: 1.0
        online

Greenlight also reported some issue on /b/admins/rooms due to timeouts.

Deployment:

1. Deployment: docker-compose
2. Versions: Scalelite v1.5.1.4; BBB 2.7.2

Expected behavior
Scalelite should detect this case.

Reproduce
No idea. In my case, Proxmox somehow paused a VM during a backup.

I'm also pretty sure this doesn't always work as intended. It's something I will try to look into after the current bulk of PRs is merged.
