After some searching i managed to solve my own issue... i needed to get inside the docker container and restart the API..
•Use docker ps to get the name of the existing container
•Use the command docker exec -it /bin/bash to get a bash shell in the container
$ sudo -u minemeld mm-supervisorctl restart minemeld-web (as per github)
Unable to create MISP miner node: Extension appears to install correctly (SYSTEM > EXTENSIONS install using git button) All versions tried Logout / Login & API restart CONFIG > PROTOTYPES > Search misp.anyEVENT - prototype not found.
Minemeld v 0.9.68 on RHEL VM
