Since updating to version 2.6.0, the two machines that I keep in sync both display the error message "Cannot get the list of trackers". I have checked everything listed at https://help.resilio.com/hc/en-us/articles/210587126-Cannot-connect-to-trackers. All the relevant ports seem to be open, and I can download the tracker address file in my browser. In any case, one of the machines is in my home, behind my router, and the other is at my university office, so the problem can't be localized to one router or location. I did not have this message before the update. Help?
