The only reason I can think of is because I am connecting from my school network rather than the my home network which I usually connect from. But I have used the same school network to connect to convex previously (a couple weeks ago or so) which makes me confused.

I appreciate any sort of assistance or insight regarding this matter.

Thanks in advance!
