Constantly logging me out of on demand services

Hi ,over the last week my box has constantly been asking me to login  to every on-demand service via my phone , netflix , 4od , iplayer , everytime I try to watch something on my  TV . If I reboot the box then its fine for a couple of hours , but later that day the same thing will happen again , I'll have to take a photo of  QR codes multiple times to watch things . If I dont it wont let me into the service or I'll get an error message saying the app is not available temporarily eg on netflix  . How do I fix this please ,I tried ringing up earlier but after 20 minutes on the phone being passed from various bot to bot and not speaking to any humans whatsoever I gave up  .
