NodeAPI 426 Error

[vricale]

Issue Description:
I am encountering an issue where any request to the NodeAPI endpoints returns an HTTP 426 status code. This happens for all NodeAPI interfaces. For example, when running the following curl command:
curl --location --silent --output /dev/null --write-out '%{http_code}\n' 'http://localhost:9010/eigen/node/health'
I receive a 426 Upgrade Required response

Please investigate this issue and provide guidance on how to resolve it. Thank you!
