Hi. From time to time i get some errors from a running archive-cronjob. It seems there is something wrong with target website but it’s not. The cronjob runs every hour for about 1 - 3 minutes over 71 sites.
Can i ignore this errors or should is there really something wrong?
Here is the text from the resulting error-log:
