FML incompatibility problem

Hey I installed two mods on my 1.19.2 server. I installed forge 1.19.2 on both aternos and my client.I checked that my mods on the server were the same as the ones on my computer. But in the side of the multiplayer menu i see a red cross on my server. When i move my cursor to the cross it says FML incompatibility blah blah blah. Please help.

By the way, here is the link to server log - https://mclo.gs/R6l4iVN

I think they are the same

Edit: My client is Tlauncher

Edit 2: I checked it. Both are same (forge 1.19.2)

see? both are forge 1.19.2

I just checked server when it is offline. It is saying vanilla server with a big white V. Please help

Ok. I realized that i forgot to download mod on my client. I have now downloaded them. But, now when I open my server, I am able to join but just 13 seconds after joining it said saving world and my game closed and the client opened. It said something about a problematic mod. Also, it still shows the big red cross and fml incompatibility but I am able to get in my world for 13 seconds. Also, my only mod is Ultimate Car Mod. Now what?
