Yes I get it all the time, right now I have been staring at the Bravo logo for the last 15 minutes.   I managed to watch 1 episode from the channel, the it went really slow, then the box rebooted and nothing.   I am told it's not the Dishtv but Freeview themselves like to blame it.   I am on ultra fast fibre but you'd think it was on an old modem the way on demand fails to perform.   I'm over it, I'm going back to paid TV.  

Still can't get in.   Had enough already, why have something you can't watch not interested in staring at channel logos for half an hour.   I've had this same issue since I moved to freeview 2 years ago, I think enoughs enough having the same issue and no progress, I've been seeing ppl make this same complaint this whole time.

i ended up giving up on my DISH TV BOX and after all this time i go into Dish on demand no trouble and it has worked for a week so far hope not speaking to soonbut all winter now programes on demand.

I now have a Panasonic HWT260 and no more problems. Works fine even just with WiFi. Have put my Dish TV box away.
