Teamviewer Slow on Fast Connection

Hawki96

Hi, I'm fairly new to TeamViewer but have had it a few months and generally use it when I'm at work to access my home PC to do CAD work. I've been using it routinely for a while and it's been fine, but I've come to use it today and the connection is very slow. I've checked the internet speed at both ends and I've got around 30 Mb/s at home and 600 Mb/s at work. I've checked the firewall and it's coming back fine, and I've checked to see if anything else is using the connection, but all comes back okay. Can anyone offer any advice?
