We are a payment service provider and have configured our infrastructure with segmented network, firewalls, etc.
Our main server resides behind a proxy server running on nginx. This is a requirement from PCI compliance point of view. But now, when we are trying to verify our domain. We are getting the below error message. Domain verification failed. Review your TLS Certificate configuration to confirm that the certificate is accessible and a supported TLS Cipher Suite is used.
Please advise on what we can do to resolve this.
