I’m currently trying to show video thumbnails on a mimic but I’m currently getting this error when using HTTPS (it's fine when using HTTP):
“Error fetching image: TrustFailure: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.”
I have also updated the DMA’s web.config file and enabled the tag “UseUnsafeHeaderParsing” but I can’t seem to get it to ignore this error.
I believe this is due to the fact that the devices certificate is not from a know certificate authority. Is there a way to configure the DMA to ignore certificate errors for video thumnails?
Certificates are used to establish a trust relationship (for example against a DNS hijack etc). Fully ignoring this trust has a big security impact. That's why the video thumbnails currently has no configuration option to ignore trust.
The recommended way is to install the certificate into the trusted certificate store of the server(s) hosting the DMA.
