Official Instance

• The bug is reproducible on the official hosted instance, or is API-related.

Describe the bug

Hello!, last week or so my private piped instance has been unable to function
i'm using the NGINX version
i followed the official guide and everything worked perfectly since a long time ago(thanks! it's amazing, i love you guys:3)

the frontend is in good shape loads and everything good, but the backend(so videos etc) doesnt work, it's in forever loading screen
i can go to login page but cant submit my account details

upon looking into the log it seems like it's getting some errors which cause it to restart multiple times over and over again (but i dont have idea what is the problem, i'm no programmer)

i was able to reproduce this in Libretube (android client) too and in different browser( firefox,ungoogled chromium)
same on desktop, it wouldnt load videos at all
also i can go to preferences tab

also it seems there's an issue with postgres too but i dont understand what's the issue

To Reproduce

1. Open url at https://piped.private.instance.example/trending
2. forewer is triyng to load

Expected behavior

everything should work as it was for couple months

Additional context

the piped instance runs in a LXC container under Proxmox
on the same instance i have Portainer and ttrss
specs of the container:

Pretty sure your postgresql database is corrupted

hmmm, and how could i resolve that? also is there stilll some way to export my subscriptions from my piped?
idk why did this happen, there was a power outage recently which turned the server off, but all the storage is redundantly stored in raid 5
please if you have any idea how to solve it that would be great! :3
