Hi, Have you set up an instance of SuperTokens core to work with?

You would normally provide a URL for this instance in the backend SDK during initialisation

How to setup an instance of Supertokens core?

jamesl

01/16/2023, 10:12 AM

I just did like this

Deleting the message since it had your API key, can you confirm that the core instance is up?

01/16/2023, 10:16 AM

can you copy the connection URI and navigate to that on your browser?

01/16/2023, 10:16 AM

do you see "Hello" message back?

jamesl

01/16/2023, 10:16 AM

Yes

jamesl

01/16/2023, 10:16 AM

I can see

01/16/2023, 10:16 AM

right. So check the backend SDk config

01/16/2023, 10:17 AM

make sure you have set the correct conntionURI in supertokens.init and the right API key

jamesl

01/16/2023, 10:19 AM

That's correct.

jamesl

jamesl

It works well in dev mode on localhost

01/16/2023, 10:19 AM

hmm. The core is working (cause you got the hello back)

01/16/2023, 10:20 AM

but your backend sdk can't reach the core.. that's weird

jamesl

01/16/2023, 10:20 AM

but when I deploy the backend on https://api.xxxx.com

jamesl

01/16/2023, 10:21 AM

frontend is https://xxxx.com

01/16/2023, 10:21 AM

do you have some firewall setting in your server that prevents outgoing connections?

01/16/2023, 10:22 AM

double check env vars.

jamesl

01/16/2023, 10:22 AM

I hardcoded the env vars for now

01/16/2023, 10:22 AM

hmm

01/16/2023, 10:23 AM

Can you see how?

jamesl

01/16/2023, 10:25 AM

I used cpanel to deploy this

jamesl

01/16/2023, 10:29 AM

if so, which port I should open?

jamesl

01/16/2023, 10:31 AM

I am using managed service, so Idon't think it's firewall problem

01/16/2023, 10:35 AM

hmm. Im really not sure what the issue could be. But something on your end is preventing your api process to talk to the supertokens core

01/16/2023, 10:35 AM

the way you have configured the connectionURI and api key seems fine

jamesl

01/16/2023, 10:43 AM

if my connection uri is https://prod-700890c1933611edb37a4d2da2eb46c0-us-east-1.aws.supertokens.io:3567/

jamesl

01/16/2023, 10:43 AM

may i need to open 3567 port on my server?

01/16/2023, 11:54 AM

you wouldn't need to

01/16/2023, 11:54 AM

cause you only need to open ports for incoming connections not outgoing

01/16/2023, 11:54 AM

instead, check for firewall settings for outgoing connections

01/16/2023, 11:55 AM

maybe also ssh into your server and run

Copy code

curl https://prod-700890c1933611edb37a4d2da2eb46c0-us-east-1.aws.supertokens.io:3567/

What do you see?

jamesl

01/16/2023, 2:18 PM

absolutely there is problem in firewall

01/16/2023, 2:19 PM

hm. So this is probably some issue with your firewall setting. Cause if you try and run this command from your personal computer (like i did), it works

jamesl

01/16/2023, 2:19 PM

Yes

01/16/2023, 2:19 PM

does the curl command work on your personal machine?

jamesl

01/16/2023, 2:20 PM

Yes

jamesl

01/16/2023, 2:20 PM

surely

01/16/2023, 2:20 PM

that means the core is working fine

01/16/2023, 2:20 PM

the fact that your server can't reach it, it means there is some issue with the server's network setting

jamesl

01/16/2023, 2:20 PM

ok let me find issue. Thank you so much for your help
