I have set the following network. I can ping my blue network from the green network as well as the middle router which connect them. If i ping one of the yellow marked ip 10.0.10.10 from the green server "INSOSV01" it works but the ip 10.0.10.9 can't be pinged.
the routing table of that middle router:
Can anyone help me out with this one ?

found the problem.I have the network 8.8.8.8/30 but in the routing table of ISP 1 as well as as the default gateway of the 8.8.8.8/30 net was wrong. I entered 8.8.8.0/24 in routing table and as default gateway of that net 8.8.8.1
Thx for the guidance.

you can attach PT file here but it must be in zip format. it will be easier and faster to spot issue.
Ping is 2 way process: to and from: you must have destination back to source. do you have static route to source and/or to destination?
My guess is that ISP1 does not know about any 192.168.x.x networks; you must add static or dynamic routing.
Remember Router knows only about its connected networks.

The Router "ISP1" has the following routing set. This router does know where to send the traffic from 192.168.135.0/24 network. You got any plan or do u see sth configured wrongly ?

normally I would do trace route on PC and router to see how far we can reach; Also, on router you can turn on debug ip icmp .
perhaps, you have a typo somewhere
