Custom Connector using on-premises data gateway throws error 500 - bad gateway

(0) ShareShare
ReportReport
Posted on by Franz30 2

I created a custom connector using https and the on-premises data-gateway.

 

When testing the connector, the test fails with the following error:

... System.Net.WebException: The remote server returned an error: (502) Bad Gateway. ...

 

When analyzing the log-files of the on-prem data gateway I can see, that the protocol for the request was changed from https to http:

 

"[ {""ConnectorType"": ""HTTP"", ""FullPath"": ""http://esap001e21.xxxxx:44301/sap/opu/odata/SAP/Z_IM_RAUMVERRECHNUNG_SRV/ZCO_ODATA_ENTITY_GET_DATASe...')""} ]",Fail,35660.50,36213,35108,DirectQuery,,,,2

 

Any ideas, what causes the on-prem data gateway to change the protocol?

Thanks a lot.

    Hi @Franz30 ,

     

    Did you find a solution for this error? I am having the same issue with the https connection through on premise gateway. 

     

    Altough both http and https endpoints are active , i cant seem to go through with https

     

    Thanks

    Hi @Enver-TR ,

    no we didn't find a solution for this. We are actually using a work-around with PowerAutomate for Desktop. This allows us to use the API from within our company network and we don't need the on-prem data gateway.

     

    Cheers
