Element iOS stuck in infinite sync with private server

[jessica1202]

Steps to reproduce

I have an infinite sync issue on Element iOS with my private server

Problem description:

I have an iPhone 12 with iOS 17.2.1.
I have a private server with 360-day self-signed SSL.
I downloaded the .crt certificate and installed it directly on my iPhone.
I installed Element iOS version 1.11.8.
I connected to my personal server and confirmed that the fingerprint is the same as the certificate installed on my iPhone.
When I connect to my private server, everything works fine at first.
However, when I close and reopen Element, the app gets stuck in an infinite sync and does not allow me to send or receive messages.

Outcome

Attempted solution:

I added the homeserver.yaml file with the following configurations:

refresh_token_lifetime: 24h
nonrefreshable_access_token_lifetime: 24h
refreshable_access_token_lifetime: 10m
session_lifetime: 24h

Result:

The solution did not work.

Help request:

What other solution can I try to fix the infinite sync issue on Element iOS?
