Distance Isochrone Gateway Time-out


I hope I am not writing a duplicate here but I have checked for other topics, there seems to be one related where there has been said to check the up time or downtime of the Car profile function but that seems to be up at the moment yet I am still getting the same error.

I am working with the QGIS plugin over the Open route server since the IT at the moment doesn’t allow me to use Docker.
When I try the car and time Isochrone (60 minutes) it always works.
Once I try and use the distance version (100km) I always get back a Gateway Time-Out (2 minutes 01 seconds):

Feature ID None caused a GenericServerError:
504 (<html> 
<head><title>504 Gateway Time-out</title></head> 
<center><h1>504 Gateway Time-out</h1></center> 

Sometimes however it does seem to work but most of the time it doesn’t, also if I reduce the range to 50km it mostly still doesnt work altrough those chances of working are quite a lot higher.

Is there anyway to solve this or am I doing something wrong?
