TLS Radsec

Hello, I'm using Radsecproxy and when I run it in debug mode, I see that it
reconnects every 30 seconds. I tried changing idle_timeout, but the same
thing keeps happening. Here's the debug log using TLS 1.3:

(0) (TLS) OpenSSL says that it needs to read more data.

In the radsecproxy debug log, the following appears:

Using TLS 1.2 also disconnects, the debug is the same except for this: (0)
(TLS) OpenSSL says that it needs to read more data.

Clients connecting to radsecproxy reach FreeRadius correctly and everything
works normally. I wanted to know if this disconnection is normal or if I'm
doing something wrong? I'm testing this to implement it later.

I'm using Debian 12.
