Missing self.socket

[cruigo93]

I am facing issue with package and I am still confusing how it was caused. So I cannot reproduce it. But here a screenshot

It seems that this issue is kinda copy of #538
pynetdicom==2.0.2

Whoops, probably a bit overzealous closing this one

I have a reproducible minimal example, pynetdicom 2.1.0, python 3.11.7, on RHEL 9. (I get a different error with 2.0.2 and python 3.8 on Ubunto 20.04 -- not sure what part matters.)

Say I am on {host} and do:
$ python3 -m pynetdicom storescp 11112

From a different host:
$ ssh -p 11112 jgray@{host}

Do that 3 times in a row. The 3rd time is usually the charm. I get:
