Hi there, this is a bit of an odd one for me and I’m not sure where to even start. I’ve successfully issued and installed SSL certs via certbot for my domain and subdomains. Everything seemed to be going great until I started experiencing random SSL drops. A couple of times per hour, my sites start displaying a “not secure” error with SSL, and when I look into this I notice that the certificate is no longer my own, but a self-issued one for a totally different website. Strangely, maybe a minute later, if I refresh the page my SSL cert is back and the site is working correctly again.
This has me totally baffled as to how this would happen. It seems to be fine then has these very random short drop-outs where a different (and self-signed) certificate for a random site shows up. Only myself and the VPS account owner have access to the server so nobody else should be able to do anything server-side.
Anyone have any experience of this sort of problem?
My domain is: eoixx.space (www.eoixx.space, pathfinder.eoixx.space, seat.eoixx.space)

My hosting provider, if applicable, is: (VPS Host) sonicfast.io
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): Manages basic VPS functions only, server managed directly via SSH
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot): certbot 0.31.0
