OBS Can't Connect to Stream Key

Hi everyone,

I'm having an issue with OBS when trying to start my stream using StreamElements Multistream.

Every time I click Start Streaming, I get the following error: https://imgur.com/a/ipatwa7

Things I've already checked:

• My stream key is correct.
• My Tiktok account is connected to StreamElements.
• OBS and StreamElements are up to date.
• I've tried reconnecting my account and restarting OBS.

I'm still unable to go live.

Has anyone experienced this issue before? Is this a problem with OBS, StreamElements, or Tiktok? Any suggestions would be greatly appreciated.
