CORS error on tracing for Domains

DevAshish-oodles commented 2 years ago

Bug description

When I am trying to configure my react app for monitoring. In the configuration if i am passing my domain it is throwing CORS error, although I have added my domain in otel configuration, but when I use IP address in place of domain it works fine.

This is the error response - "Access to resource at 'http://172.31.1.XX:4318/v1/traces' from origin 'http://172.31.52.XX/' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

Expected behavior

It should show tracing data over domain too

How to reproduce

Add the signoz url in helper file
Update the address in app.js
Hit the Domain associated with your app, and inspect the network

@DevAshish-oodles you got any solution for this?

prashant-shahi commented 1 year ago

@Gowtham029 For frontend application monitoring, you will need to configure CORS for OTLP HTTP receiver in SigNoz OtelCollector.

This ain't working. I configured the CORS policy on the collector but it isn't working as expected. This issue is open for long, isn't there any solution to this?

prashant-shahi commented 6 months ago

@stavan-vc Can you share the otel-collector configuration that you used which is not working?
