Online data access - fails

Hello, we are using Travis for a project to verify tests in the event of a change.

I create the test local on my PC and test it for errors. Data is integrated on a website. Loakl the test works perfectly.

If I upload the test to Travis, the test fails. Reason, the data is said to be incorrect at the point where I download it. But these are correct, which has already been downloaded locally several times.

Does a cache have to be emptied to keep the data up to date?

I ask for your help.

Please link to an affected build.
