Just had a look at crawler logs and the issue is :

500 Can't connect to mirrors.upr.edu:80 (timeout)
ipv4 http://mirrors.upr.edu/centos/ going in timeout mirrors

Can't reach your mirror from mirror crawler, reason why it puts it in
error state and isn't able to validate repositories and why it's absent
from the generated mirrorlists

Maybe we can take that on a thread not on this list if you want to know
the hops where it doesn't seem to work, so that you can ask your ISP
about routing issue ?
