Searching for attribute often fails

[adrianm]

A client has 50000 customers in Visma.Net.

When searching for a specific attribute it works sometimes, taking a minute or two but often fails with "An existing connection was forcibly closed by the remote host.".

This happens after 5-10 minutes so I assume it is some kind of internal timeout between the API and Visma.Net. (My timeout is 1 hour).

Is there anything I can do?

I don't mind waiting a long time for the result.

Search Url looks like:

https://integration.visma.net/API/controller/api/v1/customer?attributes={"CUST03"%3A"28"}
