Running into this same issue and this is the closest I've found to a solution. However, it appears that between Aug and now, the TS implementation may have changed (?). See my screenshot below. If I leave the Serve port blank, it defaults to 443, which is the cause of the issue. Changing to any other port doesn't solve it. I even tried typing just a space in the field but it reverted back to default when the container was created. Any guidance?
