Unable to Access Caldera Web Interface - 500 Internal Server Error in the browser

[shimsha24]

Hi,

I am new to Caldera. Currently I cloned Caldera version 4.1.0. I initially tried version 5.0.0 but I encountered few errors, so I switched to stable version 4.1.0. I’m running it on Ubuntu 22.04, VMware workstation Pro and all dependencies from requirements.txt installed without any issues. But, when I try to open the Caldera web interface in my browser, I get the following error. I’ve tried accessing it in both Firefox and Chrome. I tried these options in the browser:
localhost:8888
127.0.0.1:8888
0.0.0.0:8888
Ubuntu machine IP address:8888. I am getting the same error for all of them.

I used these commands. : git clone https://github.com/mitre/caldera.git --recursive --branch 4.1.0
cd caldera
pip3 install -r requirements.txt
python3 server.py --insecure

When I tried without --insecure flag 'python3 server.py', I got the following exception,

Thanks!

It’s working now, I found this later. Apologies! - #3063.
