I have been using realvnc for a few months. Recently it has been extremely laggy, I thought there was a problem with my server PC, so I wiped everything, installed linux mint, downloaded vncserver and it keeps asking for a license key. It used to run and ask me for my realvnc credentials. Did the binary change?
Terminal says:
Error: No license keys found.
Run vnclicense to apply the license key associated with your Enterprise subscription. [NoLicense]
