I don't see anything in your code that explains either problem (but then, you haven't told us enough (module? for instance) about your code to be sure).

However, a search for information on the error (using duckduckgo in this case) produces a wealth of information. I commend it to you, in the belief that anytime running a script kicks up an error message, one is well-advised to -- at least -- find out what the error message means.

A short-form precis of one common datum found in the many hits references above: one or more of the sites you're trying to reach has some (pretty serious) problems.
