You have a network issue it seems there's a ton of other stuff erroring in here. Vault checks curseforge for updates, not api.connorlinfoot.com - it also supresses any form of http connection failures because they're not useful.

that's the code block that checks for updates. You can verify this in your logfile by matching the numeric log statements with the plugins Vault shows as 22 in your logfile.

Closing this issue as it's invalid. There is no problem here.
