Changing Withdrawal Credentials

I am trying to change my withdrawal credential from 0x00 to 0x01. I can't seem to be able to connect to my Beacon Node. Is there another way to do it?

Be sure to use the right port used by your client. For example the default port for Lighthouse might be 5052, Avado nodes seems to use 5051, etc... If you need more help you can ask on the Discord.
