The puzzle’s difficulty is rated slightly higher due to the number of deductions required. While none of the individual steps are particularly difficult, experienced solvers can expect to spend between 45 and 90 minutes completing it.
Hello
Draw the correct path that connects both circles that are given in the grid. The path moves strictly orthogonally between the centre of cells and can not jump over walls nor intersect itself.
The path will be a palindrome line that visits each box at least once, starting in either circle and ending in the other circle. The middle of the palindrome line is marked with a diamond.
Normal 9x9 Sudoku rules apply. Place the digits 1–9 exactly once in every row, column, and 3x3 box.
Palindrome lines: Digits filled into such line read the same forwards and backwards. For example, 24342.
Killer cages: Some cells are surrounded by dotted lines, called "cages." Digits cannot repeat in a cage. The digits in a cage sum to the value in the top left.
Have fun.
Solution code: Row 1, first 6 digits.

Very nice! Also a 3 star puzzle for me, because that fits my solve time, which was 41 minutes. Thank you

This is very straightforward and approachable, so I am really not sure where the 4* difficulty suggestion is coming. This took me 15 minutes and felt like a typical 3* puzzle. 
Thanks for your comment. I made this puzzle quite a while ago but I remember some people solving this in about an hour or more. Now I am curious to other people's solving times because 15 mins is very fast I think. Also it seems like difficulty ratings on LMD are always lower than on discord.
