The inner exception indicates that this is being caused by rate limiting (code 88). This error was done in conjunction with running startstream/stopstream timeouts being too short (see https://tweetinvi.codeplex.com/discussions/573889) so presumably the verify_credentials call was over limit.
"The remote server returned an error: (429) Too Many Requests. / Rate limit exceeded,88"
Thanks.
