What is the name of the domain?
cdn2.lnk.bi
What is the error number?
ns_error_net_reset
What is the issue you’re encountering
ns_error_net_reset on Firefox for content served by Cloudflare via R2
What steps have you taken to resolve the issue?
Based on this topic: Images in CloudFlare R2 with ECH do not show · Issue #33640 · mastodon/mastodon · GitHub which seems to describe exactly the same issue, we’ve tried turning off HTTP/3 and Opportunistic Encryption. But didn’t solve.
Tried turning on/off several firefox settings, like advanced tracking protection, lower security, but nothing helps.
There are no extensions installed on Firefox, in fact the same happens with a fresh install on a new phone.
What are the steps to reproduce the issue?
Use an Android device (emulator also affected)
Use Firefox for Android (desktop version unaffected)
Open https://cdn2.lnk.bi/profilepics/-1483567_20230619454.png
The page will give error ns_error_net_reset
Note that the same exact URL works on any other browser installed on the same Android device (Chrome, Samsung Browser)
