Cannot Load my Sub's Feed on my Android Phone

I'm not sure if this is the correct place to ask this, but hope someone could tell me what's happening here.

I moderate a cluster of 5 related subs that I mainly use an android phone to access. I have no issues with 4 of the subs in moderating, posting etc.

However I'm having trouble accessing one sub, that is kind of like a reference sub for the others. It gets little traffic and very few posts, but the occasional comments and mod mail.

When I get notifications of modmails or comments I can go to the particular post via the notification but I cannot load the front page (feed) of the sub. I can still access mod tools and look in the mod log, make changes via the various tools and so on but the feed will not load.

The message is "Let's try that again. Sorry about that. There was an error loading content."

When clicking the "try again" button it says "we had some trouble getting to Reddit"

At first I thought this was just a glitch, Reddit was down or something but this has been going on close to a week now. My app is updated, I've emptied my cache, I cleared my cookies yada yada but nothing will allow me to load the feed. It loads fine on my laptop but I do the bulk of moderation on my phone.

Can anyone help me?
