Did anyone find a solution to this? I just migrated my library from a Mac to my Synology, and everything LOOKS fine, but seeing the error:
“EventSource: Failure in ParseHeader: HTTP/1.1 403 Forbidden Server: nginx Date: Sun, 09 Feb 2020 04:47:03 GMT Content-Type: text/html Content-Length: 162 Connection: close 403 Forbidden
403 Forbidden
nginx (0 - Success).”
In my logs, and streaming from Apple TV seems broken. I’ve now downgraded to 1.16 and that SEEMS to work. Transcoding also seemed broken with 1.18 with some movies. So it would seem 1.18 just doesn’t get along with the Synology (in my case a DS1019+).
