Failed to write data to connection Adress (neo4j python
I use the neo4j python driver to write to my database.
I have my neo4j DB setup and was using ita few days ago without any issues. Today i run my code and i get the following error:
Failed to write data to connection Address(host='localhost', port=7687) (Address(host='xxx.x.x.x', port=7687)); ("0; 'Underlying socket connection gone (_ssl.c:xxxx)'")
When i check via the browser and execute MATCH (n) RETURN n, it appears that all my querys still get executed bc i can find nodes in the database.
I shut my pc down, reinstalled neo4j and basically everything else. (Its not only for CREATE statements but also for match statemenets)
Adding this at the end of the script worked for me.

Asusming you're using this driver, I suspect it might be related to this bug in
neo4j-python-driver. It looks like their latest version fixes the bug, according to comments in the thread, but if not, maybe just downgrade back to whatever you were running before, and you should be fine.
It's usually a good idea to lock down your dependencies to avoid problems like this. Have a look at tools like
poetry if you're not familiar with them, they should save you a few headaches.

I'm uncertain where the issue lies, but the solve it to downgrade to python driver versions:
