Getting error "unable to find valid certification path" and question about what should be returned from the provider

[jorvis]

Trying to register a namespace but having two issues.

1. Under "Provider details" when defining Home URL I enter "https://umgear.org" and am getting this error:

Checking 'https://umgear.org' caused an error: 'sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target'
2. Under "Namespace Details" when I enter the Sample Id I get this error:

Id 'd.a59037e8' does not exist in 'https://umgear.org/p?id=d.a59037e8'

But that resolves just as it should on our site. Should it instead be returning some JSON structure or something?

Hello, sorry for the delay, I'm suspecting that it may be an issue with the page's certificate's and the restrictions on the backend verifier.

I'm not super familiar with SSL certificates but apparently, there is an issue with the verification chain.

$ openssl s_client -verify 32 -connect umgear.org:443
verify depth is 32
CONNECTED(00000005)
depth=0 CN = *.umgear.org
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 CN = *.umgear.org
verify error:num=21:unable to verify the first certificate
verify return:1

### More after this but it is unnecessary for this.

I also updated the container's certificates since the image is quite old but the problem persists. Could you check if this also happens on your end?

If there is no issue with the certificates I guess it is a problem with the verification backend like in #209.
