It looks like some IP addresses may have been banned recently, certainly not all, due to problematic bots. Unfortunately this can impact other bots which weren’t doing anything incorrect. If you let us know the name of the projects then we can review and move those like that for you.
It would also be useful to see the full error you’re getting. In prior reports the error seen due to a banned IP address was like
DiscordHTTPError: 403 Forbidden on GET /api/v7/gateway
