Hi @brocaar i have the same problem, but is it possible that you can elaborate the answers with adding endpoints and the setup by API that TLS is required?
I recommend you set first everything up without the optional TLS certificates and make sure everything works. Then you start adding them API endpoint by API endpoint and validate at every change that things are still operational
Also, when you configure TLS certificates in the config files, but leave them blank in the TLS certifcates tab in the web-interface, then it is expected that this does not work as you setup your APIs that TLS is required.
I have written almost everything here, and i can’t find a solution for the problem.
Thanks.
