Hi,
1_1_Hello_World example from your book: Build web servers esp32….. worked out fine with no problem but when I try the next example 1_2_hello… I just got error 404 website not found. Tried diffrent bords, all kind of units but nothing helps. When I upload everything looks allright. See below. I am using the code stright of the book (downloaded it)
