Actually, I just remembered that there's another potential solution that you could try. If you haven't already, you could try performing a clean reinstall of the Endpoint protection software on the affected machines. Sometimes, issues like the one you're experiencing can be caused by corrupted installation files or conflicting software on the machines.Before doing so, make sure to backup any important files or data on the machines, and consider temporarily disabling the Web Control feature during the reinstall process to see if that makes a difference.I hope this helps, and please let us know if you have any further questions or concerns.
