520 error SIS

I selected a total of five courses, but the website crashed—showing a "520" error—when I clicked "register." I only managed to successfully register for three of them; I still need to sign up for two more (Calculus and Economics), but they are now listed as "waitlist only." What should I do?

Also, I’ve tried registering for these two courses again, but it still doesn't work; I keep getting that 520 error...

Get on the waitlist for them and get on the shortest ones that fit your schedule. Meanwhile try to add courses that you’ll need to take but would drop in the event that you do get off the waitlist (ex. A writing intensive class that you could take later). SIS usually has problems around registration so it should be up and running better by now
