Some Chrome users are reporting UTORid sign in errors

Some students who use Chrome are reporting sporadic problems signing in to ACORN and Degree Explorer.

Web Login Error

We have reproduced the problem and it appears to be tied to a "prediction service" feature of Chrome. Chrome's attempt to reduce the number of web requests produces an invalid request to the login service.

We've only found this behaviour with Chrome. We have not seen the issue with other browsers.

U of T's Information Technology Services is currently investigating the issue and hopes to find fixes from the server side.
