"ClientGQLNetworkError: Internal Server Error"

It seems like very very frequently, when I click on something on Reddit (for example, upvote a post) or try to post a comment, whatever. Either nothing happens at all or I get an error like "ClientGQLNetworkError: Internal Server Error". It's been happening on multiple devices, and while at different locations.

It's been going on for quite a while now, it's pretty annoying.
