NWDS (7.31) issue at first load - timed out

Hello,

we upgraded our Portal to 7.40. According to note 1791485 - NWDS 7.3 EHP1 as development environment for SAP NetWeaver 7.4

I installed NWDS 7.31.

Problem is that first load of NWDS takes 40 minutes !!! With a lot of Timed Out message. But if I close NWDS (when finally loaded) and restart it the load is in less then 1 minute...

According to this documentation:

I checked the log file. And I found Timed Out messages:
