Give this a shot.
“I recently replaced my home wifi router after my old one died with a Linksys AC2200. Immediately after installing the new router I started getting socket closed errors on all of my eve clients at the same time(Even getting some disconnect errors on other games). So I did some exploring in the settings and linksys has this feature called express forwarding, basically it bypasses the standard port inspection to improve performance. I disabled this feature and have not had a single socket close error since. Just thought I would share incase anyone else was having the same issue.

It’s gotta be something on your end, we just need to figure out what. Try the VPN solution, post what router you’re using.
