Not able to initiate learn command

[rpandey91]

I have setup a server using docker. mosquitto, rftcp, findserver are running as per the docker output. But when I'm trying to learn the finger print from using cluster, it is returning html content of the login page. I have enter x.x.x.x:18003 as LF server, where x.x.x.x is my public IP.

Also, i am able to create a group and learn the finger print using android device.

I'm starting cluster using following command

python3 cluster.py learn -u 40:4E:36:1C:12:QC -l location1

Error
