Not playing manifest.mpd every time with Drm

Below mentioned are the implementation code and parameters used to generate the playback on my Roku 4 device. I am able to get a successfull playback with a Playready token, but only once. The second time (i.e after I return to content screen and try to play the content again) the playback could not be achieved.
I m setting Drm like Below-
ContentNode.url = “https://…s…net/secure/…lll/ff…/manifest.mpd”

ContentNode.streamFormat = “smooth”

ContentNode.KeySystem=“playready”

ContentNode.encodingType =“PlayReadyLicenseAcquisitionAndChallenge”
ContentNode.encodingKey =“http://pr.service…com/playready/…asmx”+“%%%”+ “XXXXXXXAAABw7ETd..-0YNKu…v_4vBdXPXXXXXXII0GFDL…aDcVlSx6rwGg9_xVyw6iWtTeRe8r48-mmw-XXXXXXXazCFfKnOK…l8vBvhVOhi3P”

If anyone has experienced this issue earlier, any help will be appreciated.
Thanks,
Satish

thanks for reply Michaelviomb now content is playable when content is not playable then we write a mail to express play after 1 hour(approx) my mail, content was playable may be something from there end.
