Web Gateway Error "Invalid Request : Cannot identify application path"

I want to try SAM in AWS. I followed these steps:

docker pull store/intersystems/sam:

git clone intersystems-community/sam: System Alerting and Monitoring (SAM) (

git clone


tar zpxvf sam-<version>.tar.gz

tar zpxvf sam-


$ cd sam-<version>

cd /home/ec2-user/git/sam/sam-

$ ./


In your browser, visit:
You'll be prompted to login. You can use standard InterSystems IRIS credentials like _SYSTEM/SYS. You'll be prompted to change the password.


I was able to visit and it prompted me to change my password.

Whenever I return to index.csp I only see a blank white screen. I see in console this:

I do not know if my AWS Windows instance has browser restrictions preventing SAM index.csp to display. I attempted to create my own SAM image with webserver so I can connect from outside AWS on port 443.

cd /efs/ICS/oliver/git

git clone

docker build --no-cache --ulimit nofile=8192:8192 -t sam .

Next I updated docker-compose.yml and I started sam again.

I tried to pull up or and I get 500 Internal Server Error and I see:

For a test try to give R to others on CSP.ini  and restart Apache.

did not work. still get the same error

Add one point I edited CSP.ini file (on another similar project). Cannot remember why I had tried to add


By default, only clients local to the Web Gateway’s hosting computer are allowed access to the Web Gateway Management pages. The browser through which the management forms are accessed must be running on the same machine as the web server and Web Gateway. For example:


You can add additional clients to the list of authorized administrators by adding the client IP addresses to the System_Manager parameter in the SYSTEM section in CSP.ini (in install-dir\CSP\bin). The System_Manager parameter represents a comma- or plus-separated list of clients (by IP address) who may access the Web Gateway Management pages. The directive shown below grants access to three remote clients in addition to the default local access.
