Connection Error when trying to download attachments from an older email

I am having trouble downloading an attachment from an old email from 2021. Everytime I press download it says I have a connection error.
I have a constant internet connection, and I have tested incoming and outgoing settings as well.
Is there anything else I can try/change to download this older attachment?
I am in the process of attempting to see if I can get the email off the server, if it’s still there.
