Depending on the rental server, there may be restrictions on the nighttime cron operation. In such the case, it is recommended to reduce the number of pages to be measured, so that the cron can finish its work faster.
If the error does not get resolved even if you reduce the number of measurement pages significantly, the problem may be caused by a problem with the server environment. If you would like to report a problem to the development team, please contact us and report the problem anonymously.
