Connection issues to Discord and messages not sending

[Sparoney]

Describe the bug

Hi,

Using v4.2.4 Forge on 1.20.1, the mod won't send messages anymore and keeps timing out. Was working fine yesterday. Checking the Discord status website it doesn't mention any issues. I've used your mod on the same server host before in the past and never had an issue, do you have an idea of what could be going on?

Running /mc2discord status shows no errors though:

[12:15:08] [Server thread/INFO] [minecraft/MinecraftServer]: No error

Running /mc2discord restart sometimes fixes it before it stops working pretty quickly again.

Also, attempting to run /mc2discord upload failed as well. Not sure if the mod itself is having difficulty making external connections or it is the server host's issue

Your config file

No response

After a while it'll catch up and mass send every message it missed

Also caught this error:

Seems like some connection to Discord server issue. Can you restart the discord bot and see if it solves the issue ? (/mc2discord restart)

[Sparoney]

I did it a few times in testing, it would fix it for a little bit or not at all. Not sure what is going on :(

[DenisD3D]

Maybe your host changed some proxy settings?

[Sparoney]

I’ll check with the host. In the meantime, I’ve noticed the console is coming up with an error that the channel is being updated too quickly and to increase the update delay, but I increased it to 999 from 610 and also turned it off?

[Sparoney]

Server host says there should be nothing blocking Discord or CloudFlare. I just ran /mc2discord upload and it gave me this:

I would've thought it'd just give a link lol

[DenisD3D]

The website used for /mc2discord upload is currently down but that's not preventing the mod from working.

[Sparoney]

I ended up changing to a different mod and now it is working fine
