Section 4.1.17 says:

SERVER_SOFTWARE = 1*( product | comment )

It should say:

SERVER_SOFTWARE = 1*( *( SP | HT ) ( product | comment ) )

Notes:

It seems actual usage separates products and comments with spaces such as «Apache/2.4.27 (Win32) OpenSSL/1.1.0f PHP/7.1.9».  The definition «1*rule» in section 2.1 doesn't include implicit optional (required?) spaces as a separator.

The proposed definition is backward compatible with the original.
