Some of our users experienced errors in Keboola Connection (in both regions) yesterday when saving configurations of several components.
An error was displayed to users who tried to save their configuration between Jul 9, 2019, 12:35 CET and Jul 10, 2019, 14:18 CET.
Mainly users who have an older version of Chrome Browser or any version of the Firefox browser were affected.
The issue was caused by wrong response headers (unsupported by the mentioned browsers) being sent to a preflight request on one of our API services.
We sincerely apologize for the inconvenience caused.
