Pterodactyl Server 1.16.5

Trying to install a fabric server on pterodactyl I have the egg from the GitHub repo someone else posted but every time I try to create the server it installs to the panel but then the daemon fails to install it and says it's in a failed install state and that it needs to be deleted and recreated Trying to do this for 1.16.5 MC version Have tried multiple startup commands Node and IP/port allocations are definitely fine (unless for some reason I need an 'extra' one Set all my resource managements to 0 (except CPU pinning which I left blank and Block IO Weight which I left at 500) Service variables I left as default except MC version which I changed to 1.16.5 Have tried multiple startup commands including variations of:

java -Xms128M -Xma{{SERVER_MEMORY}}M -jar {{SERVER_JARFILE}}

java -Xms128M -Xma{{SERVER_MEMORY}}M -jar server.jar

java -Xms128M -XX:MaxRAMPercentage=95.0 -jar server.jar

P.S. initially posted this as a comment on another post similar but then realised that post is a year old
