Can't "Submit and go to next challenge"

Finished a challenge and run the test successfully, then when I would normally click submit and go to next challenge, nothing happens. This is on chrome in JS section.

Additionally, when trying to login on another browser get caught in a loop wherein every time I go to the curriculum it signs me out. Perhaps these are related issues…

Yes. I suspect that there is something funky going on with the servers - either planned upgrades or some sort of problems with the service freeCodeCamp uses. I recommend saving your solution on your computer for now and grabbing a snack or taking a walk. The team is usually pretty quick to jump on this sort of thing, but sometime a solution takes time.
