Additional Context

Workaround:

r = requests.get(url, cookies=jira._session.cookies)
with open(destination, "wb") as f:
    f.write(r.content)

@RED1869 can you let me know the size of the .gif file ? We can perhaps at least add a test for a gif of similar size to see if we can reproduce this

[RED1869]

The .gif is about 530 kB in size, the .xlsx is about 50 kB. I also noticed that the response header of attachmet.get() contains 'X-Seraph-LoginReason': 'OUT, AUTHENTICATED_FAILED', whereas the response header of requests.get() contains i.a. the smsessoin cookie.
