REST API: How to prevent "An existing connection was forcibly closed by the remote host"-CodePudding

Following this thread, https://stackoverflow.com/a/2582070/6534818, I am wondering if there is any room for improvement to my REST API query that would limit the frequency to which I receive the following error: "An existing connection was forcibly closed by the remote host". The thread suggests, as one possibility, that the query is malformed.

My general setup for a query to Azure DevOps is as follows:

# Access Token
pat = "secret_token_here"

# authorization encoding
authorization = str(base64.b64encode(bytes(":"   pat, "ascii")), "ascii")

# url
url = "https://dev.azure.com/org/project/"

# REST headers
headers = {"Accept": "application/json", "Authorization": "Basic "   authorization}

# GET
response = requests.get(
    url=(url   "_apis/wit/workItems/%s/revisions?api-version=6.0" % str(work_item)),
    headers=headers,
)

I tend to suffer this issue when running this in a loop, perhaps every 4th or 5th total run, looking up each item of interest.

CodePudding user response：

There can be many reasons for the issue:

The network link between server and client may be temporarily going down.
running out of system resources.
sending malformed data.

To examine the problem in detail, you can use Wireshark.

or you can just re-request or re-connect again.
