CORS issues

See original GitHub issue

Hi guys,

just want a report a server configuration issue (I don’t know where to put this, so I opened a github issue). Occasionally, when using Branch web SDK I get CORS errors.

Console output (I removed some data from output):

XMLHttpRequest cannot load https://api.branch.io/v1/has-app/MY_KEY?browser_fingerprint_id=xxxxxxxxxxx. The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed. Origin 'http://localhost:9000' is therefore not allowed access.

We’ve recently went from v2.1.1 to v2.11.0.

Hope you will be able to track down the server responsible. Thanks!

Hi @tech-sgsragasagara! Sorry you’re having difficulties with the service. We’ve done a check against your app id and don’t see any errors like this for it over the past several days. Of course you’re seeing the issue, so there must be something going on, and we’ll try to help where we can.

Does the problem you’re seeing happen very often? Also do you have a timestamp for when you see the errors? Any extra information would be great to help us track this down.
