Glide taking longer time in specific wifi connection for specific URLs

When I connect my mobile with ```OPPO A15``` hotspot the cloudfront CDN urls are laoding late(25 seconds). The URL loads well in other wifi connection. At the same time other application such as Instagram and Youtube runs well in that ```OPPO A15``` hotspot as well as random URL form internet loads well in that ```OPPO A15``` hotspot connectivity.

I don't know whether it is Glide library problem or Hotspot problem or URL problem. The URL is [https://d1qm53daoujrb6.cloudfront.net/600x340-scion-01.jpg](url)
