Kodi, Amazon Fire Stick 2, Diskstation UPNP

I’m having an issue with Kodi i just cant for the life of me figure out. I am running Kodi 16.1 off my Amazon Fire TV Stick 2. My Upnp server is a Synology Diskstation, using the standard built in diskstation. Kodi will not stay connected to the UPNP server. Every other device i have that streams using DNLA works just fine. Other upnp apps on the Amazon Fire TV Stick 2 work fine. But Kodi is giving me issues. If i reboot my Synology Diskstation or go and reset the UPNP device list in the diskstation, then Kodi can see the Diskstation and DNLA streaming works just fine, until i exit out of kodi. Once i exit out and start it back up, i can no longer see the Diskstation UPNP server on the network and any attempts to connect to it error out ONLY in kodi. I get “Couldnt Connect to network server”, but then if i reboot the diskstation or reset the device list it works again until i exit out of Kodi. Other devices i have with Kodi dont have this issue, like my samsung galaxy phone or my nvidia shield.

Any idea’s on how to fix this?
