Hi Pulkit,
Have you checked your SSL settings? One Docker user who reported the issue in the past turned out to have SSL issues which could explain your case. We do have a Troubleshooting guide that mentions a proxying issue that can cause this but it wasn’t really targeted at Docker users (you may want to update your Docker image just in case however).
I’m unable to replicate the problem unfortunately, so if fixing the SSL configuration or updating the Docker image doesn’t work, could you please try attaching your API definitions to this ticket (you can export APIs to JSON format using the yellow button on the “Edit API” page)?
Kind regards,
Jess @ Tyk
