Authentication works on mlapi server but no detection

[mcs1998]

Hi,
I was hoping someone could help me. I just installed mlapi on an external server to my Zoneminder installation with a running zmeventserver to reduce the load on the zmeventserver. The zmeventserver works fine, but I cannot access the mlapi server. While I can connect to the zmeventserver and the mlapi starts, if I use:
sudo -u www-data /var/lib/zmeventnotification/bin/zm_event_start.sh 510903
I get an empty response when I use:
ml_fallback_local=no
otherwise the normal response form the local detection.
Also, nothing is logged on the mlapi server.

When I test with cli access I can obtain a token but if I use the picture with:
curl -H "Content-Type:application/json" -H "Authorization: Bearer ${ACCESS_TOKEN}" -XPOST -d "{\"url\":\"https://upload.wikimedia.org/wikipedia/commons/c/c4/Anna%27s_hummingbird.jpg\"}" http://localhost:5000/api/v1/detect/object

I received back:

{"msg": "filetype .html not allowed"}

in the mlapi server I get back:

(trapped) error reading bcrypt version

Similar with the other curl examples.

mlapi version:2.2.24, pyzm version:0.3.64

Any help would be greatly appreciated.

Cheers
