'Cannot open connection to' error #75

Closed DieterPi closed 1 year ago

DieterPi commented 1 year ago

I've made an exercise where data is downloaded from KMI and analysed in R. However for the feedback the following error appears

Error while evaluating context: cannot open the connection to 'https://www.meteo.be/resources/climatology/uccle_month/Ukkel_waarnemingen.txt'

How can I resolve this?

Are you sure you enabled the network for your exercise? The error seems to point in the direction of no internet being available.

By default, network access is disabled for the docker containers where the tests are run. You should set network_enabled to true in the config. See https://docs.dodona.be/en/references/exercise-config/#config-file-structure-for-exercises for more information.

This fixed the issue, thanks for the quick response!
