👋 Hello, team! I am getting started with self hosted growthbook deployment and trying to deploy it on a EC2 instance. but facing the issue where it can not connect o API's. I did updated the environment variables as per the docs. can you please help to figure out what's wrong?

Hi Dheeraj
Are you getting any errors in the console?
And can you test going to that API url directly?
n
going to api url directly gives cors origin issue as it is not expecting my personal ip as origin
console and network errors
f
that is not a request directly to the API
can you open the port 3100 url directly?
if its working it should give you a json object back
n
it will give me cors origin access issue
I found the issue.
by looking into logs of docker compose
f
cool, what was it?
n
you should probably update the docs to change 
ENV
to non prod and 
JWT_SECRET
is mandatory for PROD
It was asking to provide a random key for 
JWT_SECRET
f
ya, if you don’t change it, we throw an error

it wasn't mention anywhere in get started doc
f
ya, I’ll make it clearer

thankyou so much

Updated the self configuration documentation. Added this:
When using GrowthBook in production, it is important to change the 
NODE_ENV
to to “production” and change the 
JWT_SECRET
to a random string. Using the 
production
node environment and the default 
JWT_SECRET
will throw an error.

great. thanks @fresh-football-47124
Just wondering if I provide 
APP_ORIGIN
and 
API_HOST
it by default assume that's its a prod environment right?
f
We thought about that, but there are cases where that is not true

I am getting this issue now. Adding NODE_ENV and JWT_SECRET didnt seem to help

Anyone have any ideas. It was working until I added NODE_ENV and JWT_SECRET.

Can you go to the url of the API directly? If it's working, you should get a json object
e
I get a 502 error
f
That seems like the problem- if your running in docker, are their any errors in the console there?
e
I have an error in the logs about using JWT_secret=dev being not allowed.
But, I have set that in my docker-compose.yml file.
f
Sounds like it hasn't pulled in those changes
e
is 
docker-compose restart growthbook
an appropriate way to get those updated?
f
@future-teacher-7046 do you know?
e
Looks like
Copy code
ENCRYPTION_KEY=<long-string>
Is required as well.
Alright, that should probably be somewhere in the docs. Its working again.
f
@proud-baker-47556 is that new?
Great! Glad you got it sorted
e
Still have the issue of multiple 
Access-Control-Allow-Origin
rows.
I was hoping messing around with the ENV variables would resolve, but alas.
f
That's from the front end request?
e
Yes: Calling it from insomnia 
<https://growthbook-api.fm.co/api/features/><key>
Also from react:
Copy code
useEffect(() => {
    // Load feature definitions from GrowthBook API
    fetch("<https://growthbook-api.fm.co/api/features/><key>")
message has been deleted
f
The API only sends a single access control header. Do you have nginx or another reverse proxy in front? It's possible that is adding a second one
