Online check failing

[pettijohn]

Using ER-X, upgraded firmware from 2.0.9-hotfix.6 to .7. After upgrade, Wireguard did not come back online.

Further debugging, copying the onlinecheck command but replacing -s with --verbose

Resolving timeout. But host api.github.com works

$ host api.github.com
api.github.com. has IPv4 address 140.82.116.6
Host api.github.com. has no AAAA record
Host api.github.com. has no MX record

Increasing or removing --connect-timeout in the curl command fixes the glitch. I'm not sure what is causing curl to take so long to connect or resolve the name. The host command completes in 4ms.
