2023-04-11 17:36:19,442 | WARNING  | failed to load data from url=https://atlas-cric.cern.ch/cache/ddmendpoints.json, error: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)> .. trying to use data from cache=/var/lib/boinc-client/slots/0/agis_ddmendpoints.agis.ALL.json

Task eventually falls back and runs without agis_ddmendpoints.json file, but it wastes time in beginning and end.

I was able to install cern root certificate and modify job.xml but it gets reset each time computer restarts.
