Cant connect system with the same fluids.

[Sporedd]

I am playing a modded game. No major overhaul mods, just quality of life mods.
Both are base game Petroleum gas
I disabled all mods and reloaded the game
Still cant connect two fluids

Rebuilding everything seems to work, but im 100% sure that it is the same fluid.

Seems like as soon as some gas is produces before conneting it to the station this pops up.
Had it again with the result product of cracking.

Have you checked the two pipe system you want to connect?
If you click on any pipe it will tell you which fluids are in that pipe network. One of the pipe networks most likely contains more than only petroleum gas. In the very same window you can flush the polluting fluid. If flushing once does not resolve the issue, you have to figure out where you have fluid mixture in your base.

Left pipe goes to chemical plant that produces sulfuric acid and is connected to water input. Due to how pipes work, this makes water fluid system and petroleum fluid system to merge so left pipe is seen as having water in it. Not a bug.
