Inquiry Regarding SHA-256 Used for Partner Registration

When registering a partner, I entered the following SHA-256:

C5:8A:73:D1:B8:C0:2C:8F:D9:98:67:48:F6:EA:72:03:8E:A7:85:D0:83:BC:B1:68:C9:EA:3A:0B:55:62:67:D1

However, when making a data call, the following error message occurs:
2003: com.gchc.combination does not match with registered signature. C5:8A:73:D1:B8

Is there something wrong with the SHA-256 I registered?

Please confirm.

Package name: com.gchc.combination
SHA-256: C5:8A:73:D1:B8:C0:2C:8F:D9:98:67:48:F6:EA:72:03:8E:A7:85:D0:83:BC:B1:68:C9:EA:3A:0B:55:62:67:D1
