When you try to log in to mydish.com what exctly is happening? We do have a few known issues but some have workarounds. There is also the MyDish app if that can work for you.
We do have a known issue where the password section is grayed out or does not allow you to type in it. The workaround that we have listed is to try another device besides the computer. What type of device is this and what is the OS?
