Dial tcp: i/o timeout when accessing CF API endpoint in project piper using custom Jenkins setup

[tarun053]

Hi,

I'm using this Custom Jenkins as part of project piper, however I'm not able to establish the connection to the CF API endpoint. There is no proxy necessary in my network.
I tried same directly from linux server and command 'cf login' gives me timeout error but 'CF_DIAL_TIMEOUT=15 cf login' works fine. Any ways to add CF_DIAL_TIMEOUT in parameters.

Setting api endpoint to https://api.cf.eu10.hana.ondemand.com...
Request error: Get https://api.cf.eu10.hana.ondemand.com/v2/info: dial tcp: i/o timeout
TIP: If you are behind a firewall and require an HTTP proxy, verify the https_proxy environment variable is correctly set. Else, check your network connection.

My first question would be if this issue persists for a longer time. I guess it might always be that something reacts slowly but that should not be a normal state. I would not want to increase the timeout to then forget about this. How many times have you tried the cf login? On which days?

And what do you mean with "custom Jenkins"? Does it make use of the cx-server script? Is it running in Docker? Or is it some "custom" Jenkins in the sense that it is setup from scratch?

@fwilhe
I tried several times however same issue, i am never able to get a success with cf login.
By custom Jenkins i mean, local Jenkins with plugins installed at my server. Not using Jenkins from Piper docker image. Also scripts are of piper library
Hope this is what you asked
