@dompap our CI is picking up some URL error with https://human-settlement.emergency.copernicus.eu/

The error is Error: R] https://human-settlement.emergency.copernicus.eu/ | Network error: SSL certificate verification failed. Check certificate validity

Full log is https://github.com/PCMDI/input4MIPs_CVs/actions/runs/19555296779/job/55996260068?pr=392

Do you want to check before we merge? Or is this not your issue?

@znichollscr the link seems to work correctly on the browser (including the certificate) so maybe it was temporarily offline at the moment of the check.

Hmm still not happy (https://github.com/PCMDI/input4MIPs_CVs/actions/runs/19555296779/job/56183190472) but that's ok. I'll handle it another way.
