That would surprise me.

See it as an envelope: HTTPS puts the signed file in an envelope without 
changing the files. When the envelope is received the original file is 
taken from the envelope. Normally, no bytes are changed in the process.

In your case, bytes were changed (otherwise the signature wouldn't be 
invalid). Compare both files on the byte level and you may get one step 
closer to diagnose what changed those bytes.
