NAV OData Connection - Authentication error

(1) ShareShare
ReportReport
Posted on by 39

I'm trying to connect Dynamics NAV OData with PowerApps, but I'm getting an authentication error saying that the username or password is incorrect.

I'm using Windows credentials, and I was able to connect to SQL Server.

For OData, I need to enter the URL, username, password, and company name.

I entered the same username and password that worked for SQL Server, so that should be correct.

SSL is set to false, so I've confirmed the URL is correct, and the firewall is open as well.

Then, the only thing that could be incorrect is the company name.

I entered the company name that appears when I type 'companies' in NAV, but I'm still getting the authentication error.

I'm using Dynamics NAV 2018. What could be causing this issue?

 

Also, the OData Object Types are Page and Query. Could this be causing the problem?

 

+ Does the integration between NAV and PowerApps work only with NavUserPassword authentication, not Windows?

+ Also, the version of NAV I use is 13.0. Is there any possibility that this version doesn't support PowerApps?

    I have seen you raise similar issues many times in the forum, but it is still not resolved. I suggest you submit a SR to Microsoft and let the support team assist in the investigation.
     
    Hope this helps.
    Thanks.

    My work MS account logged me out from the Service Hub with the message, “Sorry, we're unable to sign you in at this time.”

    For the questions I’ve posted before, I’m asking again if new issues come up after previous ones have been resolved, or if I didn’t get the exact answer I needed. In those cases, I try to provide clearer details about my situation.

    Since I can’t submit an SR right now, this community is currently my only option. If possible, could you help me with this issue?

    Thank you for your help.

    Okay, I think there are two possible issues left. One is a server issue. You can install it on another PC and try again.
    The second is a NAV 2018 version issue. Try the latest CU.
     
    Hopefully other experts can give you better advice.
     
    Thanks.
