Possibility of Malwarebytes Blocking Twitch IRC Port?

Recommended Posts

Hi, for weeks my Elgato Stream Deck, although it can connect to Twitch, it has issues sending chat message. After running their diagnostic tool, they told me that something is blocking the port, Twitch's port is 6667 and their support team told me to check if Malwarebytes is blocking it. I don't know how, can someone help?

Malwarebytes doesn't block any specific ports, however, if there is a specific server that the chat component uses and that server is in Malwarebytes block list then it could be what's blocking the connection.  You can check this by right-clicking on the Malwarebytes tray icon and clicking Web Protection: On and then clicking Yes if prompted by User Account Control to temporarily disable Web Protection.  Once that's done, try connecting and using the chat feature to see if it works.  If it does, then it is the Web Protection component blocking it which means you should probably exclude the program from Malwarebytes web blocking to allow it to connect to any server that it needs to.  If it turns out that this is the case, then here is how you exclude a program from Web Protection:

  • Open Malwarebytes and navigate to Settings>Exclusions
  • Click on the Add Exclusion button
  • Select Exclude an Application that Connects to the Internet then click Next
  • Click on the Browse... button then navigate to the location of the program's file/process that connects to the server that is being blocked and click once on it to select/highlight it then click Open
  • Click OK and the process should now be listed in the Exclusions tab and should say Application Web Process under the Exclusion Type column
