I use NS8 (latest) and was not able to generate a request or upload a cert. The msg was something went wrong… P.S. it would be nice to have the ability to find out the NS8 version (core, …) for maintenance and debug errors.

You could add the Windows CA root/intermediate certs to the trusted cert store on the host. This is the preferred way IMO as you can just upload the certs as you did before without disabling any verification in ns8-traefik. Export the CA certs, see also Export Root Certification Authority Certifica…

You need to upload a certificate including the chain of certificates:

Request / Upload TLS-Certificate
