Sup, due to wear I replaced the chain of my mechanical ultegra road bike. It has a 50t chainring and a 30t cassette. so I adjusted the chain to 104 glides. Now it elevates above the spikes at like every 360 degree turn and jumps back at like 450 degree turn. Already tried to adjust the shifters with H and L, the alignment seems to be fine. Is the chain actually too short? Any idea what to try next?

The quicklink is not fully locked, that’s why your chain lifts from the chainring.
What is the length of the previous chain, when everything was fine?
Your quick link is not fully engaged, the upper pin must go all the way

The quick link is not engaged all the way.
Have you put the correct chain on for how many gears you have?
the chain lock is not engaged
Your quick link hasnt fully engaged yet and is causing the gap between the rollers of the chain to sit in the wrong place. Find the quick link, move the chain so the link is somewhere between the cassette and chainring, then stand on the pedals to make it seat in fully then it should pedal like normal. Best of luck! The Shimano quick links are very tight to engage compared to others
That quick link isn’t closed so it’s made a short link which doesn’t fit over the teeth
Check it’s lined up correctly just not all the way. Back up the chain so the link is on the top, hold the brakes and put weight on the pedals. It will pop into place.
Put the quick link joint between the rear and front derailleur. Grab the rear wheel with one hand and turn the crank with the other, the quick link will pop into place. I did this exact change this afternoon 🤣🤣🤣
