Unable to access to TAC URL on studio

[DOCA01]

Hi, 

I'm working with Talend verion 6.3

when I'm trying to open a job, I got this message : une erreur est survenue (Unable to access to url)

I can access on tac with browser and I don't have any problems in manage connexion

 

I added this line in studio.ini :  -Djava.net.preferIPv4Stack=true, but nothing happens

thank you for help.

Have you tried connecting via the TAC IP address rather than the host name? Depending on your DNS/Hostfile setup it may be that Talend cannot resolve the hostname correctly.

After your proposition, I tried it but it dosn't work
