TLS Enabled server Core Connection Error after random time

[only-su]

I enabled TLS and setup it on my core

2024-08-20T01:01:45.005829Z  INFO TLS enabled
2024-08-20T01:01:45.005863Z  INFO Lodestone Core live on [::]:16662

I then created a new core connection on https://www.lodestone.cc/ using https and informed my host. I didn't had my router port open so I got an error. I then unblocked router port and it successfully went to login screen.

After login I got 1 second of connection, the green Connected flag on top right corner, the TLS lock on url shows everything is all right. Then a pop-up Core "Connection Error". Reloading the page would give the same 1 second of connection an then error.

After that I ctrl+f5, that seemed to solve the issue I could have some time of connection. But I was happy to soon.

Now the "Core Connection Error" happens on random intervals, a simple F5 connects me again but it's not permanent.

I use Floorp a Gecko based browser but can confirm it also happens on firefox.
