The program that generated this message has a problem.  First it
announces that the signature hash is going to be SHA1:

Then it provides the signature:

Digest algo 8 is SHA256, not SHA1.

You might be able to manipulate things into verifying the signature by
editing the file to change the SHA1 string to SHA256, but the real
problem is probably in whatever program generated the message.
