@khaled Would it be possible to share curl output here (mask ip and other confidential details)

curl -v https://mcsvc.dynatrace.com:443

Check error log here -- Installation directory -> Server.*.*.log

Add an SSL certificate to Dynatrace Managed cluster TrustStore

1. Get the .pem version of the certificate assigned to Proxy.

openssl x509 -inform der -in certificate.cer -out certificate.pem

2. Run the reconfigure.sh command.

nohup <PRODUCT_PATH>/installer/reconfigure.sh --update-cert --network-proxy-cert-file <cert_file>.pem &
