FireFox is connecting to my website, but accessing already visited pages would randomly not connect resulting in a
Secure Connection Failed
Chrome and Microsoft Edge are not having that problem.
What is strange is that reloading the page is also not working. I need to force reload the page by way of using Shift and reload - and then I get the page back, and will always load when using shift and reload.
How can I prevent this from happening?
The html pages are pre-compresses Brotli files served by an Apache 2.4.57 server.

I am using these default Connection Settings in FireFox:
SSL info when the connection is not made and I get a ns_error_net_interrupt
error:
SSL info after reloading that same page (using Shift and reload) -- it works again:
