Plain React application running on localhost

[Herlix]

Hey!

I've got a scenario where I am running an app under localhost and it is supposed to send info to sentry. This does not work as I get CORS issues. I've set the allowed origin to my domain and to '*', this does not help. Is this an effect of me not having a server side component for routing the sentry data?

My setup does work for my other nextjs projects.

I've got the app hosted behind an nginx, could I update this server to help with the CORS issue?

Hi, can you check whether your ad-blocker is active? https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSDidNotSucceed

Ad-blockers have unfortunately chosen to block requests to Sentry. This can be circumvented with tunneling: https://docs.sentry.io/platforms/javascript/troubleshooting/#dealing-with-ad-blockers

There's no addons in the browser on the machines running the app itself.

I tried turning everything off on my local machine and I now get a forbidden instead. (403).

I've checked that the DSN is ok.

What do you mean by this? You should check that the browser you are using does not have an ad blocker.

I tried turning everything off on my local machine and I now get a forbidden instead. (403).

As a response from Sentry? That usually shouldn't happen unless you deleted your org or your project in Sentry, or you fumbled copy & pasting the DSN.

The DNS sees to be right and the browser is reset so there is no addons what so ever. This now gives me the 403.

I've seem to have found the problem. It was code related 🙈
