Hello
I developed an application and one of the components allows to retrieve information from a gene on NCBI serious to a web request
I have never had any problems so far yet since today and without having modified much it works once out of 2
The request is not huge and I did a lot of testing. Before it worked very well with input tests and now with input tests it works once out of 2.
Here is the mistake I have.

My code has always worked and I don’t think it comes from him because sometimes it works and sometimes it doesn’t.
Moreover when I test my orders locally I have no worries
If anyone has a solution 
Thank you
