I haven't checked all of the sample request/responses, but it looks like the app is URL encoding the redirect location. You could add URI decoding to the iRule to handle this: 


when HTTP_RESPONSE {

    Check if server response is a redirect and contains the wp-admin pattern (with URI decoding of the Location header)
   if { [HTTP::header is_redirect] and \
      [string match -nocase {*www.server.com/*/wp-admin*} [URI::decode [HTTP::header Location]]]} {

       Log original and updated values
      log local0. "Original Location header value: [HTTP::header value Location],\
         updated: [string map -nocase "http:// https://" [HTTP::header value Location]]"

       Do the update, replacing http:// with https://
      HTTP::header replace Location [string map -nocase "http:// https://" [HTTP::header value Location]]
   }
}
