Dear building professionals,
The wall connection of my cold conservatory is leaking in several places. Water is dripping inside onto the wall. In the photo, you can see that I have already added a sealing tape (black) to the silicone joint between the conservatory and the house wall. Could the cuts in the lip seal at the crossbars be the cause? It is visible that the seal does not properly rest against the glass there. Can water penetrate through wind and capillary action at these points? How can I fix this? Would a cover strip still be useful? However, for example, I would need to use thermal insulation anchors for the polystyrene insulation. Would that help? At the moment, I rather think the lip seal is the cause. Should this lip seal be completely replaced without cuts? I have already received an initial indication that the cuts and gaps in the lip seal are suspicious. How is this supposed to be installed correctly, that is, how can it seal tightly against the glass?

I removed the windowsill above because I have the impression that water drips not only on the exterior facade but also on the interior wall of the conservatory at the window front during winter. I will provide a requested photo from the inside soon. But: how should I reinstall this windowsill and seal it properly? The house was built in 1997. The conservatory is from Aylux—I could say a lot about that… I either have to fix it myself or hire professionals, but no one wants to do it, even though it’s been tried already…
I wanted to add that it looked dry underneath the metal sheet. Here is the interior view
There is moisture in 2-3 spots along the yellow roughcast facade and additionally on the brown window. This seems to have occurred before the conservatory was installed, as the paint is already flaking in these areas. Could this be caused by the leaking window sill above?

OK, thanks for your suggestions. I have now temporarily covered all the cuts in the lip seal with duct tape (yes, sorry, but this is just for testing). I also checked under the lip seal and noticed some pollen residues/dirt particles at the edge of the glass towards the wall. If the wind can carry these in, then water probably can as well. After the last rain, everything remained watertight.
So here is my question: how do I seal the cuts properly?
1. Request a new lip seal about 5 meters (16 feet) long from Aylux (warranty), which could be problematic (construction time over a year, multiple rework appointments, price reduction...)
2. Use sealing tape, rubber strip, or ???
