Problems with establishing connection to UA Server

Post by jonasthiel »

Dear community,
based on "GettingStarted_VS2015" project I tried to create my own UA-Client in my application. Right now I have a problem with the initial connection to the UA-Server:
sometimes the "data.session.Connect(data.endpointUrl, data.security)" throws an error: "Error establishing a connection." (see attached Picture [Error message content]). If I put this funtion call into a while loop, the client connects after a few tries (see attached Picture [debug file content]). Because of the fact, the client connects sometimes, I do not have any clue where to locate the problem.
Is it possible to configure a bigger timeout?

May you help me? Thanks alot in advance!

Kind Regards,
Jonas

Edit: I'm not able to add any Attachement, because the "board attachment quota has been reached".
