Use of Proceed and Proceed further?

The two words are ‘Proceed’ and ‘Further’.

I want to know the diference between “Proceed” and “Further” when they are used together and separately.

e.g.

1. The login functionality doesn’t work. We can’t proceed to the next page.

2. The login functionality doesn’t work. We can’t proceed further to the next page.

I think the use of the word ‘Further’ is redundant here.

Proceed already means go further/farther; continue.

I just saw the word Proceed. You can see there is one sentence “Before we proceed further, does anyone have any questions.”

Is this sentence wrong?

What is the exact differrence when only “Proceed” is used and both “Proceed” and “Further” are used altogether?
Thanks
