Telly not parsing M3U/XML + Plex can't find it (Synology NAS)

telly release with the issue:

telly, version 1.1.0.3 (branch: dev, revision: cec8d730177b15a6d1f60d879d2db493f9de51a3) build user: root@7a0e0684991b build date: 20180905-23:20:50 go version: go1.10.3

Last working telly release (if known): first install

Operating environment (Docker/Windows/Linux/QNAP, etc.):

Synology DSM6.2 & Linux Ubuntu 19.4

Description of problem:

Can't get Telly to work on my Synology NAS.

When starting the program in Terminal on my Synology I get the error seen in the log. Tried Telly on Ubuntu and I'm getting the same errors (once in a while it parses the M3U without errors) When trying Telly on Windows, it just works...
When trying to find Telly (Windows) in Plex (running on Synology), it doesn't find it... When entering the IP of my NAS I get the error: "There was a problem adding the device..." (see attached screenshot)
