I get dominated by 1.d4 How to fix?

I get dominated by 1.d4. In particular here on lichess. On chess.com I'm actually crushing my opponents who play 1.d4. Which is pretty weird.

I assume it has something to do with me playing against 1.d4 just way less than 1.e4, but even against 1.c4 (even rarer, as you know) I'm doing pretty good, so I don't know if it is that.

So my first question is this actually an issue or just a sampling problem? And to that I say I have about 250 games (on lichess) against 1.d4, so I don't think the sample size is too small. But when I do combined my lichess and chess.com games, the problem does disappear, so maybe too small of a sample size is a valid concern.

If it is a problem, do I need to pick a different repertoire against 1.d4? Or do I perhaps need to stick with my current one, but just analyze/memorize deeper into the lines?

And why do results on chess.com vs lichess vary so much? Has anyone else experienced this, or is this just me?

Well, seems you play the 1. d4 f5 and 1. d4 c5 most of the time: Both are not really good openings.

Which opening as black do you like most against 1. e4 ? Based on that we could propose something similar against d4 (solid or aggressive, open or closed ... depending on your taste).

As black against 1.e4 I play ...e5 2.Nf3 Nc6 and eventually i try to break with either f5 or d5 and prefer to attack the kingside (if the white king is over there). if possible I like to castle opposite my opponent and throw everything at them like that.

Hm, that is difficult. There are no openings against d4 in which opposite side castling is common.

"Throwing everything at them" can mean

1. at their king: Than the usual choices are indeed the dutch or the kings indian. Within the dutch which you play you can check other options than the Leningrad with g6+d6 which you seem to prefer. The Stonewall tries to allow a king side attack by keeping the center closed. The classical dutch does not include g6 which keeps the way open to throw also the queen against the white king with the standard moves Qd8-Qe8-Qh5. In contrast to the dutch with g6 it also allow to involve the rooks more into the attack e.g. after castling kingside you can play Rf8-f6-g6/h6 ideas. Simon Williams plays the classical a lot: You may like his Youtube-channel "GingerGM"

2. at their position but not neccessarily their king: Aggressive options are the Benoni or the Wolga-Gambit or the Albins-Countergambit, but their problem is that they are not as universal as dutch and kings indian setups which can also be played against 1. c4 and 1. Nf3.

Maybe watching how GingerGM plays the classical dutch without g6 is the best next step. Here is a link to his last video in case you don't know him (first game is a dutch :-) ). If you search on Youtube for "GingerGM Dutch" you will find special videos about the opening.

Yeah, at their king.
Thanks man, I really appreciate you taking time to analyze my stuff.
I was also thinking switching to a Dutch with e6 instead of d6 and g6 might be the way.
So in short you think the answer might be in a repertoire switch up.

If you want a tactical game, you can go for Tarrasch and either von Hennig-Schara gambit or Dubov variants. (You'll also face a lot of Londons after 1. d4 d5)
Or something like Benko/Blumenfeld.
It's hard to guess what you'd enjoy so I'm just throwing spagetti at the wall to see if something sticks. Bill

probably pure coincidence - at your level you get crushed for many lacks of insight to the game...

You may like Simkn Williams "The Killer Dutch Rebooted" from 2022 (follow up tonhis earlier Dutch book). It is available as book and course.

Play white I suppose.

if you check his game results you will find that he scores much better against 1. e4 than against 1. d4 . So it seems there is really something going on and he is not as good in the types of positions he achieves after d4. That is a sign that you should either study the opening type better or change it ... and the Leningrad Dutch is for sure an opening which is diffiult to play.
