Server Version#: 6.2.1-23824 Update 4
Player Version#: 1.14.1.5488-cc260c476
Had the Plex Server running on this new setup - then decided to download the update (listed on the Plex site).
Now it doesn’t work.
I traditionally use Safari, but have also tried using the DSM on Chrome and uninstalling and downloading/installing again on there. I have also tried rebooting the NAS, to no avail.
There is no Firewall Enabled on the device and I am still having issues.
Any thoughts? Probably doing something simple wrong - but need help. 
Thanks
