I have a Slingbox Classic which has the latest firmware. About once a month, when I try to connect I get a "Connecting…" message on multiple versions of SlingPlayer and it just won't connect. Eventualy a dialog box says check firewall, connection etc. A day later everything is fine. The issue occurs with direct IP connection and also Slingfinder. I have no Internet outages at the remote location or Slingbox, and can verify this by pinging. There are no variables at the Slingbox location for time of day etc. The internal network at the Slingbox is wireline with Belkin HD, also on the latest firmware. Any ideas? Please don't point me to existing content relating to ports and configuring remote viewing, etc. I've been doing this a long time and have multiple Slingboxes.
