Cannot set X509 finger print for IoT Edge/IoT Device on Azure Portal

Question

I have made iot edge certs according to https://learn.microsoft.com/ja-jp/azure/iot-edge/how-to-create-test-certificates?view=iotedge-1.4&tabs=linux

$ ./certGen.sh create_root_and_intermediate
$ ./certGen.sh create_edge_device_identity_certificate "XXXX" 

And, I get fingerprint from command, like below

$ openssl x509 -in XXXX.cert.pem -fingerprint -sha256 -noout

SHA256 Fingerprint=XX:YY:ZZ:CD....:20

I try to register IoT Edge on Azure Portal, put value " XX:YY:ZZ:CD....:20" at "Primary Thumbprint",

then same error always occurs.

error message is "Invalid X.509 thumbprint."

What went wrong?

Answer 1

I figure out by myself...

It goes well, when colon(":") is deleted.
