DataSource.Error: Received an unexpected EOF or 0 bytes from the transport stream.

Hi

Yesterday I created a query, which takes data from these tables:
https://data.gov.lv/dati/eng/dataset/gada-parskatu-finansu-dati/resource/27fcc5ec-c63b-4bfd-bb08-01f...
https://data.gov.lv/dati/eng/dataset/gada-parskatu-finansu-dati/resource/50ef4f26-f410-4007-b296-220...
https://data.gov.lv/dati/lv/dataset/gada-parskatu-finansu-dati/resource/d5fd17ef-d32e-40cb-8399-82b7...

https://data.gov.lv/dati/eng/dataset/gada-parskatu-finansu-dati/resource/1a11fc29-ba7c-4e5a-8edc-7a2...

 

Based on "id" I merged these four tables into a single query. 

Yesterday everything worked fine. Today, when I refreshed the query, I got this error:
"DataSource.Error: Received an unexpected EOF or 0 bytes from the transport stream."

What could be the reason for this error and how to solve it?

Thanks for the help!

It seems to me, that it might be somehow related to the internet speed. When I use the query in work office, it works, in home office, it doesn't.

Hi @maasool ,

As far as I know, this error might be related to the certificate validation issue with SSL. Since it works differently in the work office and home office, you can try to compare it in this point.

Hi! Thanks for the new idea.

Can you elaborate on how could I investigate this certification validation issue and what could I do, so it won't be a problem in the home office?

Best regards

Not so much the speed, rather the reliability. The error message hints at a potential package loss.

 

You can add try ... otherwise ... to your code for an instant retry.

I used 4 English version data sources 

I mean merge.

you have three english and one latvian data source?

When you say "merge" do you mean "append"  ?
