Can't Connect with Nitro in a Retro

[thauanvargas]

Hey, so I'm trying to connect into a Retro, but i'm not able to with Nitro, with Flash works.

Host: https://ironhotel.org

Flash:

• IP 144.217.125.146
• Port 4431

So basically i've tested @UnfamiliarLegacy fix at #149 in Windows 11 64bit
When I runned that version of G-Earth and tried to connect Nitro I faced the problem of Untrusted Certificates on the website (see bottom of this issue), then I runned certutil install_certs.bat from @WiredSpast and it worked, I could sign in in the Hotel.
Tested running Chrome in Incognito, it seems it's closer to connect to the hotel rather then the most recent version of G-Earth (1.5.3) as when you start connecting, it shows the Hotel Version. But the behavior is still weird, sometimes it blinks the Hotel Version, sometimes don't...

I tested build in https://github.com/sirjonasxx/G-Earth/actions/runs/4702547020
And also tested running with a cherry-pick with commit hash 16749e9 from #149

Found the following errors:

Screenshot if not running install_cert.bat

Note: this happens when you try accessing all pages , so you are obligated to run install_certs, I don't know if this is a good approach, so either there is some bug for me which is not adding the certificates correctly when I press the following message.
As it always asks this too, but maybe this happens because I run a modified OS where I run everything as administrator, I don't know.
