Hi @BarnacleBob , could you help resolve this?

[BarnacleBob]

At the core this error is that curl returned a non 0 exit code on a test fetch of the passed url while trying to detect if it needs authorization or not. i would need to see the output with bash +x to see whats happening, but since this is run through mlc i dont know how that would be passed. The test call looks to be just curl -sS -kI --max-redirs 0 --retry 3 --retry-connrefused --connect-timeout 3 --max-time 12 "$url". You could also try that to see what might be happening locally.
