"Error: failed to detect signature algorithm" during first sync with signaturealgorithm = auto in the profile聽#226
Description
"Error: failed to detect signature algorithm" during first sync with signaturealgorithm = auto in the profile. Able to continue after setting signaturealgorithm to HmacSHA1.

what if there is not a setting signaturealgorithm in the cmk config ?

@weizhouapache when signaturealgorithm is not there in the profile, cmk added this - "signaturealgorithm = HmacSHA1".

@sureshanaparti
the issue is because apikey/secretkey is wrong in .cmk/config
in the past or signaturealgorithm = HmacSHA1, if the apikey is wrong, it will fall back to use the username/password
now with signaturealgorithm = auto, cmk will fail with
failed to detect signature algorithmplease retry after cleaning up the apikey and secretkey in .cmk/config
