CORS error on API calls (via browser)

[sharkykh]

I'm getting CORS errors on a webapp:
Access to fetch at 'https://api.trakt.tv/sync/playback' from origin 'https://sharkykh.github.io' 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.
The origin https://sharkykh.github.io is listed on the API app settings, so that seems to be a server issue.

The response to the preflight request (OPTIONS) is 403 Forbidden.

I am experiencing the same issue. When did you start encountering this?

Something appears to have changed on the back end as my app has been working successfully for years until this issue popped up a couple of days ago.

When did you start encountering this?

A user reported it yesterday.

@rectifyer any chance you could look into this? In the past you have helped resolve some CORS related issues.

I'm getting the same issue here. Getting it from last 24 hours.

The response to the preflight request (OPTIONS) is blocked by Cloudflare

As of 36 hours ago it was working again, and it is still working now.
I'm calling it fixed, unless someone else still has the issue.
