'IOS simulator - certificate .pem from cert bot not working - @apollo/client 61: Connection refused

When I try drag&drop my cert.pem generated with certbot then I get this error: One or more parameters passed to a function were not valid.

Simulator IOS 15.2.

Anyone already this problem?

I converted certificate from .pem to .der but this certificate is not displayed in simulator settings :/

Solution 1:^[1]

I updated certbot certificate on the server API and now connection works without certificate on the simulator and device
