I wanted to make a discord relay bot for my server, so I followed this guide: https://github.com/ClassiCube/MCGalaxy/wiki/Discord-relay-bot. However, on server startup, it said

Error sending request to Discord API (POST /channels/1393772596650053733/messages)

!!!Error (The remote server returned an error: (403) Forbidden.) - See Logs tab for more details

Discord API returned: {"message": "Missing Access", "code": 50001}

And when I looked at logs, there seemed to be a long string of incomprehensible gibberish, which I have added below for your discretion.

Type: WebException

Source: System

Message: The remote server returned an error: (403) Forbidden.

Has anyone experienced this before or knows how to fix this? Thanks.

I think you did not enable the message intents in the settings for the bot on the Discord developer panel.

I did, it's message content intent, right?
