Unable to connect to to Kernel on Chrome

Hello,

The connection to the Kernel on Notebooks keeps failing. I have adjusted the Privacy settings in Chrome to allow third-party cookies, and added dynoquant.com and quantopian.com to the browser´s whitelist however I still get the following errors:

Access to font at 'about:blank' from origin 'https://research-i-099b58de5ed12d8ef.prd.int.dynoquant.com' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

TeX-AMS-MML_HTMLorMML-full.js?V=2.7.8:70 GET about:blank net::ERR_FAILED

kernel.js:461 WebSocket connection to 'wss://research-i-099b58de5ed12d8ef.prd.int.dynoquant.com/user/581a4478a16cf3d8ab0002e8/api/kernels/569ff511-9530-46d1-99fc-2187150be66c/channels?session_id=7daa9f867c0d4c8898d562032c70d965' failed: Error during WebSocket handshake: Unexpected response code: 400

I hope someone can help me out with this, Thank you very much,
