HTTP 502 when trying to download from opendap.cr.usgs.gov/opendap/hyrax

(Hi, me again with another OPeNDAP issue. By the way, I'm Kodi Arfer and I work at Mount Sinai Health System on environmental-health research. Nice to meet you.)

I've tried building queries with the Hyrax web interface at

https://opendap.cr.usgs.gov/opendap/hyrax/MCD19A2.006/h00v10.ncml.html

and for many requests, such as

https://opendap.cr.usgs.gov/opendap/hyrax/MCD19A2.006/h00v10.ncml.ascii?Optical_Depth_047%5B0:1:5%5D%5B0:1:0%5D%5B0:1:5%5D%5B0:1:5%5D

the server hangs for 1 min 30 s and then responds with HTTP 502, Proxy Error. Curiously, other requests seem to work fine, such as

https://opendap.cr.usgs.gov/opendap/hyrax/MCD19A2.006/h00v10.ncml.ascii?Latitude%5B0:1:5%5D%5B0:1:5%5D
