Your two sites don't work for me without using a VPN or proxy.
I also have 100% packet loss when trying to ping cmd against your sites.
It seems your hosting provider is blocking Crimean IP addresses or something like that.

Can you access https://cf.tom5454.com/ without a proxy or VPN?

It seems to work)

GitHub gists are not going away. The mod uses the minecraft's proxy settings, that comes from the launcher to access the paste site. (These proxy settings are also used for minecraft's authentication).
But I will add an option to the settings gui to change the proxy for the paste site.

please don't give up on the GitHub gists and add the ability to use a proxy to connect the mod to paste.tom5454.com.
Otherwise, people like me simply won't see other people's models.

99% of the fault was the sanctions as your sites are located on google servers.
