Hello @mikecousins, just to check, do you see this error only in Chrome or in all browsers?

[mikecousins]

Yes only on Chrome and Edge (also Chrome).

For the original I think there either may have been a back-end problem or some missing detail, for example a proxy. This more recent report looks maybe ldcli related and not related to anything with the SDK. If this header is restricted or not is determined by other headers, which LaunchDarkly services should be setting correctly.
