I personally have never had issues running games when myself and two of the players are all on the same internal network while others players are not in the house, so all I can do is offer some suggestions and our troubleshooting guide. Firstly, what happens if you roll back to Chrome 62? Others have been reporting issues with Chrome 63 and Roll20 so perhaps this is falling under that umbrella. Secondly, where are you located physically in the world? Perhaps your ISP is having routing issues. Thirdly, you wouldn't believe how many times this fixes things, would you please carefully work through the first three steps of our guide to Solving Technical Issues ? Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log, starting at table loadup!) Thank you!
