Some infrastructure servers cannot be contacted error in NWDI

[Former Member]

Hi,

I am trying to import a development configuration from the NWDI server and it all works fine and i am able to create the projects too. However, it all works fine the first time. If i log off and try to log in again, it fails and doesnt login to the configuration and it ends up with a warning saying: Some infrastructure servers cannot be contacted.

What could be the issue. Please help.

Ciao,

Manoj

Restart NWDS and work on it, It will solve it temperorily.

We faced this issue. Later on we found that CE server connection was very slow/poor.

When we try for standard ping (also from command prompt) it sends 32bytes payload but when you increase it to 512 which practical it shows 'connection timed out' error..

So go for n/w check by network team. This resolved our issue.

Hi Mahesh,

I dont see any entries in the log file of the NWDS. if i am not wrong, you mean the log file stored in the .metadata file of the workspace right?

@Patraleka,

I tried all the options mentioned in the link you provided. None of them worked. I deleted the .keyring2 file too. But that too didnt work.

I have the same issue and no real solution for that. Only workaround is to restart the nwds (File-->Restart) and log on again. Then it works.

For the second time when you try to login again... try to ping the SLD from NWDS. Let me know if that shows any error.

Hi Mahesh,

It pings all fine. There is no trouble pinging from NWDS the first time or even the second time.

Both NWDI and NWDS are on the same version and SP level?

Can you check if the nameserver is maintained in a different host? When you import the configuration it will display all these details...probably the name server is on a different host and you don't have access that host.

Dear Manoj,

or

2)You can delete  all the entries and enter them all new.
