Freeswitch Invalid profile [External]: 2002

Question

I installed Freeswitch and fusionPbx using docker. here is the docker file:

FROM ubuntu:20.04

#ARG DEBIAN_FRONTEND=noninteractive
ENV TZ=Asia/Tehran
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# Install Required Dependencies
RUN apt-get update \
    && apt-get upgrade -y \
    && apt-get install -y wget
RUN wget -O - https://raw.githubusercontent.com/fusionpbx/fusionpbx-install.sh/master/ubuntu/pre-install.sh | sh \
 && cd /usr/src/fusionpbx-install.sh/ubuntu && ./install.sh
#RUN wget -O - https://raw.githubusercontent.com/fusionpbx/fusionpbx-install.sh/master/debian/pre-install.sh | sh \
#&& cd /usr/src/fusionpbx-install.sh/ && ./install.sh
USER root
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf
COPY start-freeswitch.sh /usr/bin/start-freeswitch.sh
VOLUME ["/var/lib/postgresql", "/etc/freeswitch", "/var/lib/freeswitch", "/usr/share/freeswitch", "/var/www/fusionpbx"]
CMD /usr/bin/supervisord -n

the docker is working fine and running. and is running using below command:

docker run -dit -name fus5 -p 80:80 -p 443:443 -p 5060:5060 -p 5080:5080 fus_ew:0.5

Problem:

the problem is that when trying to connect to an external sip gateway, give the below error when I hit the start button:

Freeswitch Invalid profile [External]: 2002

Appreciate it if anyone can help.
