@chrishadley We found the issue. Its unrelated to the issue we already fixed, but would have the same timeout symptoms. We will get a fix out asap and I will report back. (Thanks for the detail about results after 500 being the issue, that was the magic detail that narrowed it down for us).
@romsnesrom This might be the source of your issue as well.
This should now be resolved, thanks for all the reports. We believe it was being caused by Comic Vine's own network provider misidentifying the CVS app as a threat. They have removed the signature causing the issue.
