Cannot login to RTO

Xueying · September 2021

I have just received RTO machineID account. I set password and created AppKey. However, when I tried to login, there is an error. I am not sure what is the reason. Can you please help me? Thank you. I use CPP Real Time SDK on Linux environment.

Hi @Xueying

As per our offline conversation;

Looking at the source code for our API (rsslRestClientImpl.c), the text ‘Error: Failed to set CURL options with text’ is from our API and the following ‘an unknown option was passed in to libcurl’ is coming from the Curl library.

You can also google ‘an unknown option was passed in to libcurl’ to find possible solutions to your curl library issue.

I can confirm I have tested your credentials with both a Windows and Linux version of Cons113 and with a Python script and all 3 instances are able to login to the server.

Hi @Xueying

Please try the following and post any error response here - do NOT post MachineID, Password, AppKey or any Access token here.

curl --location --request POST 'https://api.refinitiv.com/auth/oauth2/v1/token'; \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Bearer ' \
--data-urlencode 'username=<Machine ID>' \
--data-urlencode 'password=<Password>' \
--data-urlencode 'grant_type=password' \
--data-urlencode 'scope=trapi' \
--data-urlencode 'takeExclusiveSignOnControl=true' \
--data-urlencode 'client_id=<App Key>'

Also, please confirm which EMA CPP example you are running? Are you following the QuickStart steps?

Hi @Xueying

Please note the similar error message from another user was as a result of the executable not being able to locate the OpenSLL and curl libraries at runtime - Help running the consumer example - Forum | Refinitiv Developer Community

Hi, @umer.nalla , this is the response. BTW, I used Proxy when connecting to RTO.

I used the same program for RTO Trial months ago and I only changed credentials now, so I think there should not be any problem regarding to the code.

umer.nalla · September 2021

Hi @Xueying

For Proxy related issues, you would need to seek assistance from your internal network/security team - who can also interact with our RTO team via the helpdesk.

Can you confirm your MachineID looks something like GE-A-01234567-8-9101 and the password, is the long password set using the link in the Welcome email (that also contained the above MachineID)?

The above error indicates you are using an incorrect username and/or password

umer.nalla · September 2021

Hi @Xueying

By New Credential, do you mean a new MachineID?

If so, did you set a new password for your new machineID?

Xueying · September 2021

Yes, it is a new machine ID and I set new password for it.

umer.nalla · September 2021

Hi @Xueying

I have tried your machineID and password with the Cons113 example and I am able to connect and consume data.

Therefore, the issue is likely to be a local configuration issue or an application issue.

Please test with Cons113 as suggested earlier and confirm the credentials are valid.

Xueying · September 2021

Thank you. It turns out to be some problem with curl library. I did not use the right version of libcurl.

Xueying · September 2021

Hi @umer.nalla ,

Now I use a new machine and when I do cmake in the SDK , there is some error. Could you please help to see what is the problem? Thank you.
