You might encounter authorization problems or server disconnections if you're using the Webroot SecureAnywhere software.
Webroot support team informed us that this is due to the version ending in 27.49 (the latest one) blocking the network peripherals. Webroot is working on the fix but it won't be available until the next version of their software releases.
Right now, the easiest fix is uninstalling or disabling their software, but that's far from perfection. Webroot Support recommends reaching out to them for help if you're affected.
Contact Webroot Technical Support at 1-866-612-4227 during normal business hours for over-the-phone help. Webroot's Customer Support business hours are 7:00 am to 6:00 pm, MST, Monday through Friday.
