I would love to fix this, most people who have this issue are using enhanced privacy/tracking protection settings that block the reddit url or have VPN/proxies turned on. Unfortunately reddit blocks that traffic in the guise of preventing spam/scrapping.
Now I can put up a server and bypass the traffic through my VPS and make the reddit content available to rdx(which libreddit used to do before reddit tightened their API). But soon enough they will ban my server, I will have to buy another and this keeps going on and on. That will be too much effort for too little gain.
However if there are already some servers that make the reddit JSON available through some proxy, I am all for adding it to the app. However I couldn't find anything that will even last a week.
I see, yes my Firefox is hardened, I'll try it without the use of VPN, and report back
side comment : it sucks how these tech giants are ruining "the open web" and making it less accessible, making knowledge less accessible in the process
