When you try to activate licenses for CMS, an error message pops up "Activation failed due to network. Please try again."
If more than 100 license serial numbers are sent in at the same time, this error message will occur.
Please register fewer licenses at a time (less than 100 serial serial numbers). For example if there are 110 serial numbers, please register 50 first. Once it succeeds please register the other 60 next.
