as previously discussed, your internet connection is an outlier - most people (even schools) have a competent internet connection to load these images easily
Obviously you're using Ultraviolet - I'll assume you're making your own proxy
What version of Ultraviolet are you using? Can you send a screenshot of the error you're getting?
There is an issue template for a reason - please give us more context
1. Where are you using Ultraviolet? If testing locally, what version are you using?
2. What site are you trying to visit?
Ohh loading Cloudflare sites inside proxies - I’ve had luck using Libcurl transport but it varies sometimes, plus this is would be an issue best opened in the Ultraviolet repository
