502 bad gateway error - On Prem SQL Database

Hello All, 

 

I am trying to create a flow to export data from an on premi sql database and then import it into an excel spreadsheet. 

 

When trying to run the flow I am getting a 502 Error, status: Bad Gateway. I have used this gateway for file connections on prem and it works OK. Setting up the flow I am able to see the table I am trying to retrieve, so I would presume its ok. 

 

I have also tried using another gateway installed on a different server, and I am getting the same error. 

 

Has anyone else experience this, or has a way to resolve it. 

 

Thanks in advance.

Re: 502 bad gateway error - On Prem SQL Database

Hi @Tyrrell94 ,

The error code 502 indicates that the failure is temporary or transient. 

As the error message said, you have used the Incorrect syntax near the keyword 'FROM'.

Could you please share a screenshot of your flow's configuration?

 I have made a test on my side, and the flow works will:

Re: 502 bad gateway error - On Prem SQL Database

Hello, 

 

Thanks for your reply. 

 

I tried it again this morning and I am still getting the same error.  I have attached an image of the setup of my flow. It is set up as you have shown, but I am still getting the same error, which leads me to believe it could be a problem with the gateway? Am not sure really, I can't see why it wouldn't be working. 

 

Kind Regards,

Andrew

Hi @Tyrrell94 ,

Could you please share a full screenshot of the run history with the error message?

You can rebuild the connection without gateway for a try.

Re: 502 bad gateway error - On Prem SQL Database

Hi @v-zhos-msft ,

 

Here is a screenshot of the error after it has run. I don't believe I can use this connection without a Gateway as it is an on-prem database? Unless I am wrong with that.
