Curl command working in 12.2 but not in 13.3

Hello, 
one my teammate is trying to put some obversability on our Databricks flows.
When he tries to contact our Open Telemetry server, he gets a timeout.
I had a look, and the same command (on the same Databricks workspace) works well with runtime 12.2.
It does not run in 13.3 (or above)

%sh
curl https://otel-<something>.com

"curl: (28) Failed to connect to otel-<something>.com port 443 after 129793 ms: Connection timed out"

II have no idea how to explain it.
Has anyone experienced a similar problem? ?

Thanks for you help.
