Well there isn't much that I can recommend as again, we don't appear to be blocking the crawler, they seem to just be having problems with the pages themselves (in fact even the error states "client error." A "client" in tech terms is usually the viewer, such as a browser or a web crawler).
With that said, you have a few options available. First off, despite the long list of URLs, it is in fact only 4 posts which are having issues according to the pdf which you provided. Given that your site has 108 posts and 14 pages, that may not matter as much to you. If it does, you can try renaming them (make sure the slug is updated as well) and have the crawler run again. If it is important that the crawler be able to finish the run without any errors but you don't care if the posts are included in the results, you can set them to draft and then have the crawler run, that way it should not see the pages.
Those are the steps which I can think of that you can take on your end. Unfortunately there's really not anything which we can do ourselves.
