Hello @Naresh and welcome to the community !

Could you please share the following:

• the logs from your agent as you are trying to connect on forest
• in the network tab does the CORS preflight request receive a response?

Additionally can you try running a curl to your agent ?
curl -v [your-agent-endpoint]/forest

[matthv]

The issue is most likely happening upstream of your agent.
Could you check your nginx/reverse proxy configuration to ensure that:

• OPTIONS requests are properly allowed
• CORS headers (Access-Control-*) are not being filtered

Could you check your proxy logs to see if the OPTIONS requests are reaching the proxy and what’s happening to them?

@Matthv This is even happening for local environment where is it trying to reach localhost:.

Request is not reaching to server and even preflight request is failing.

Hello @Nilesh, thanks for the update.

Recent Chrome/Chromium versions require explicit user permission for a remote site.
Can you look if you have given the local network access permission to app.forestadmin.com ? New permission prompt for Local Network Access  |  Blog  |  Chrome for Developers

Please also try loading Forest Admin:

• in private navigation with all extension disabled
• on another browser

To definitively check if your agent is reachable locally and responding correctly, could you try to execute the following command
curl -i -X OPTIONS -H "Origin: https://app.forestadmin.com" -H "Access-Control-Request-Method: GET" http://127.0.0.1:PORT/forest

@matthv Thank you. Permissioning local area connection helped resolve issue with Local Environment. @Naresh Can you verify if this resolved issue with other environments as well.

HI @Nilesh @matthv I have confirm with the users who were facing the issue. After granting the permission to local network, all envs are working as expected. Thanks.
