Authenticating to Splunk cloud causing "Unexpected DTD declaration. Line 1, position 3."

praveenp — Thu, 21 Oct 2021 16:11:39 GMT

I've created a trial account in Splunk cloud and I am trying to create index using the Splunk client C# SDK and when I try to login it throws "Unexpected DTD declaration. Line 1, position 3."

var service = new Service(new Uri("https://prd-p-8298m.splunkcloud.com")); service.LogOnAsync("sc_admin", "password").Wait();

I tried to change the port to 8089 as well but this caused "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond." error

Any help on this would be appreciated.

Thanks in advance

Have you verified that port 8089 is open already? I would check this outside of the SDK first.

This can be done with telnet if this is windows:

telnet prd-p-8298m.splunkcloud.com 8089

The port is not open.

Got the following message from telent

"Connecting To prd-p-8298m.splunkcloud.com...Could not open connection to the host, on port 8089: Connect failed"

Can we enable that port in splunk cloud?

Yes port 8089 can be opened. You just need to file a support case.
